実験手順

In a microwave vessel, methyl 2-bromo-3-thiophene carboxylate (1.0 eq, 64 mg, 0.29 mmol), 2-amino phenyl boronic acid (1.2 eq, 48 mg, 0.35 mmol), sodium acetate (3.0 eq, 71 mg, 0.86 mmol) and PdCl2(dppf) (0.1 eq, 15 mg, 0.028 mmol) were mixed together in anhydrous DMF (0.2 ml). The mixture was heated in a microwave oven at 120° C. for 5 nm. The material was purified by preparative HPLC. Acetonitrile was evaporated, and the compound was extracted with CH2Cl2 (3×). The combined extracts were washed with water, dried over Na2SO4, and the solvents removed in vacuo. Recrystallization in EtOH provided thieno[3,2-c]quinolin-4(5H)-one as a tan crystalline solid (7 mg, 12% yield). LCMS (ES): 95% pure, m/z 202 [M+1]+; 1H NMR (CDCl3/CD3OD, δ: 1, 400 MHz) δ 7.28 (m, 1H), 7.33 (m, 1H), 7.43-7.50 (m, 2H), 7.74 (d, J=4.4, 1H), 7.82 (d, J=7.6, 1H) ppm
