反応手順
The title compound was prepared according to the procedure described in step-2 of Intermediate-7 by using methyl 5-amino-2-methoxybenzoate (15.0 g, 0.082 mol), stannous chloride (37.25 g, 0.16 mmol), sodium nitrite (6.28 g, 0.091 mmol), conc. HCl (400 mL) and water (100 mL) to afford 14.0 g of desired product. 1H NMR (300 MHz, DMSO d6): δ 3.75 (s, 6H), 7.09 (m, 1H), 7.20-7.23 (m, 1H), 7.34 (s, 1H), 10.20 (br s, 2H); MS (m/z): 197.27 (M+H)+.
