Source of material

The methyl 4-[(4-aminophenyl)amino]benzofuro[2,3-d] pyrimidine-6-carboxylate 7 (2.0 g, 6.0 mmol), 4-cyanobenzoic acid (1.15 g, 7.8 mmol), HATU (systematic name : 1-[Bis(dimethylamino)methylene]-1H-1,2,3-triazolo[4,5-b]pyridinium 3-oxide hexafluorophosphate; 2.96 g, 7.8 mmol) and Et3N (1.2 g, 12.0 mmol) were stirred together in dimethylformamide (15 mL) at room temperature for 7 h. Upon completion of the reaction, the mixture was diluted with saturated sodium carbonate solution (50 mL) and subsequently extracted with dichloromethane. The extracts were combined, washed with brine, dried over anhydrous Na2SO4, and concentrated in vacuo. Purification by silica-gel column chromatography provided 2.13 g the desired product. After slowly evaporating the solvents for several days, some light yellow single crystals were obtained.

Experimental details

The structure was solved by direct methods and refined with the SHELX crystallographic software package [1]. The hydrogen atoms were placed at calculated positions and refined as riding atoms.

Comment

Cancer is one of the most health problems in the world; although many classes of drugs were used for the treatment, the needs for safe and effective anticancer compounds are still significant target. Heterocyclic building blocks represent useful scaffolds for applications in medicinal chemistry. To our knowledge, 4-anilinopyrimidine derivatives often have a wide range of biological activities, especially in antitumor drugs [4, 5]. Some of them have been developed as the important prescription antitumor drugs in the market, for example, Pazopanib [6], Ceritinib [7], Brigatinib [8], afatinib [9] and rociletinib [10] are all based on 4-anilinopyrimidine.

The title molecule (see the Figure) has a benzofuro[2,3-d]pyrimidine skeleton, in which all bond lengths and bond angles fall in normal ranges [11]. The dihedral angles between benzofuro[2,3-d]pyrimidine and two phenyl rings are 62.46° and 20.25° respectively. And the two phenyl planes are not coplanar with a dihedral angle of 64.08°. Furthermore, a mass of the intermolecular hydrogen bonds N(3)–H(3A) ⃛ N(4), N(3)–H(3A) ⃛ N(4), C(14)–H(14) ⃛ N(1), C(4)–H(4) ⃛ O(3) and C(11)–H(11) ⃛ O(4) are found in the title structure. It is worth noting that the crystal packing is further stabilized by weak p-p interactions (3.5142 Å). These interactions together with intermolecular hydrogen bond result in the formation of a three-dimensional framework.
