Application of 1088994-22-2 ,Some common heterocyclic compound, 1088994-22-2, molecular formula is C12H10N2O2, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.
Compound 3-1 (100 mg, 0.26 mmol), compound 5-1 (58 mg, 0.28 mmol), HATU (150 mg, 0.39 mmol) and DIEA (124 mg, 0.96 mmol) were dissolved in 5 mL of DMF, and the mixture was stirred under room temperature for 3 hours. The reaction mixture was poured into aqueous saline and extracted with ethyl acetate (10 mL x 3). The organic phase was combined and washed with water (10 mL x 2) and saturated NaCl solution (10 mL x 2), dried, filtered and concentrated to give a crude product. The crude product was separated by preparative HPLC to obtain compound 7-1 (30 mg, white solid, yield: 20%). 1H NMR (400 MHz, MeOD) delta= 8.78 (dd, J=4.9, 9.7 Hz, 2H), 8.17 (d, J=8.2 Hz, 0.5H), 8.11 (d, J=7.9 Hz, 0.5H), 8.01 (d, J=3.1 Hz, 0.5H), 7.75 (br. s., 0.5H), 7.57-7.50 (m, 0.5H), 7.43 (d, J=8.2 Hz, 0.5H), 7.38-7.31 (m, 2H), 7.26 (s, 0.4H), 7.13 (s, 0.6H), 6.86 (dd, J=3.5, 9.0 Hz, 0.5H), 6.36 (dd, J=3.5, 9.0 Hz, 0.5H), 4.77-4.72 (m, 0.5H), 4.21-4.11 (m, 1.5H), 3.78 (br. s., 1H), 2.52 (br. s., 1H), 2.46 (s, 1.5H), 2.35 (s, 1.5H), 2.09-1.95 (m, 2H), 1.91-1.37 (m, 7H)
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1088994-22-2, its application will become more common.
