Source of material
To a suspension of the 8-bromo-2-oxo-2H-chromene-3-carboxylic acid (5.0 mmol), HOBt (1.01 g, 7.5 mmol) and pyrazole (0.51 g, 7.5 mmol) in CH2Cl2 (20 mL) was added DCC (1.03 g, 5.0 mmol) at zero centigrade and stirred for 15 min. The reaction mixture was warmed to room temperature and stirred for 24 h. Upon completion, the mixture was filtered through celite, and washed with CH2Cl2 (10 mL) and concentrated in vacuo. Then, the crude product was subjected to flash column chromatography on silica gel (petroleum ether/ethyl acetate = 3:1) to afford the product.
Experimental details
The carbon-bound hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms with d(C–H) = 0.82–0.95 Å, Uiso(H) = 1.5 times Ueq(C) and 1.2 times Ueq(O).
Comment
Coumarin and its derivatives are important bioactive compounds [4–7]. Therefore, the synthesis and modification of coumarins have always been a hot topic in the medical field.
The title compound contains one coumarin, one bromine atom, and one acylpyrazole group. The bond lengths and angles derived from the title structure are within normal ranges and consistent with those reported previously in similar structures [8], [9], [10], [11]. The C=C bond was determined at the distance of 1.338 (6) Å (C8–C9). The keto group was confirmed by the distance of 1.200(5) Å (C7–O2), and the alcohol hydroxyl group was identified by the distance of 1.203(5) Å (C10–O3), respectively. The bromine atom was determined at the distance of 1.883(4) Å (Br1–C5). The pyrazole group attached at the C10 atom is twisted out of the coumarin plane with C8–C9–C10–N2 torsion angle of 118.4(4)°. The pyrazole group was confirmed by the distance of 1.362(5) Å (N1–N2), distance of 1.324(6) Å (N1–C13) and distance of 1.341(6) Å (C11–C12), respectively.
