1 Source of material

The title compound was prepared using a multi-step approach via one pot reaction. Firstly, malononitrile (9.90 g, 0.15 mol) was dissolved in dilute hydrochloric acid (151 ml), After undergoing nitrification, rearrangement, and dehydration reactions, then add sodium chloride (10.40 g, 177.8 mmol), 29 ml of 6 N hydrochloric acid, 60 ml of acetic acid, and dropwise addition of sodium nitrite (4.00 g, 58.0 mmol) to obtain intermediates through diazotization reaction. The intermediates then react with 3-bromo-4-fluoroaniline and N, N-carbonyl diimidazole, respectively. The products were washed once with 60 ml of 1 N hydrochloric acid, 60 ml of water and saturated sodium chloride solution, dried with anhydrous sulfuric acid and filtered. The product was oxidized in 30 ml of 30 % hydrogen peroxide solution, 90 ml of trifluoroacetic acid in an oil bath at 45 °C and then reacted with 4-methylphenylethylamine, and the reaction was shown to be completed by thin layer chromatography (TLC) (petroleum ether: acetate = 4:1, v/v), and the final product was deprotected under alkaline conditions. Crystals were obtained by slow evaporating a mixture of dichloromethane and methanol (1:1, v/v) at room temperature.

2 Experimental details

The structure was solved with the olex2.Solve structure solution program using Charge Flipping and refined with the SHELXL refinement package. The Uiso values of the hydrogen atoms of methyl group and hydroxyl group were set to 1.5 Ueq and the Uiso values of all other hydrogen atoms were set to 1.2 Ueq(C).

3 Comment

Indoleamine 2,3-dioxygenase 1 (IDO1) is a heme containing enzyme that catalyzes the cleavage of the tryptophan ring to N-formylkynurenine in the pathway of kynurenine metabolism, and is a key rate limiting enzyme mediating this metabolic pathway. 5 The compounds in this report were designed and synthesized as novel N-hydroxyamidinium derivatives by structural modification of side-chain aminosulfonamides based on the structure of the crystal complex of Epacadostat with IDO1 enzyme in combination with a similar molecular structure that has been previously reported, 6 , 7 using Epacadostat, an IDO1 inhibitor that is in phase III clinical trials, as a lead.

The crystal structure is monoclinic, with an asymmetric unit consisting of one molecule (Figure) which comprises four planar groups, namely: benzene ring (A: C1–C6, Br1, F1), N-hydroxyamidine (B: C7, N4–N5, O2), furazan ring (C: C8–C9, N2–N3, O1) and methylphenethylamine (D: C10–C18, N1). In the crystal structure, the bromine and fluorine atoms are bonded to the benzene ring with C(3)–Br(1), C(4)–F(1) bonds, respectively. The C(3)–Br(1), C(4)–F(1) bond lengths were determined as 1.882(3) Å and 1.353(3) Å. In addition, the bond length of N(2)–O(1) and N(3)–O(1) on furazan ring are 1.409(3) Å and 1.377(3) Å, respectively. The bond lengths and bond angles all fall within the normal range. 8
