Yield: 97%
Reaction Conditions:
with thionyl chloride at 80; for 5 h;
Steps:
77.1
Step 1. Methyl 4-amino-5-chloro-2-methoxybenzoate A solution of 4-amino-5-chloro-2-methoxybenzoic acid (30 g, 148.80 mmol) and thionyl chloride (35.1 g, 296.95 mmol) in methanol (400 mL) was stirred 5 hours at 80° C. The reaction mixture was concentrated in vacuo, diluted with water (200 mL), extracted with ethyl acetate (2*200 mL), dried over anhydrous magnesium sulfate, and concentrated in vacuo to afford methyl 4-amino-5-chloro-2-methoxybenzoate as a pink solid (31.3 g, 97%). LC/MS (ES, m/z): [M+H]+ 216.0 1H-NMR (300 MHz, CDCl3) δ 7.84 (s, 1H), 6.30 (s, 1H), 3.85 (s, 3H), 3.84 (s, 3H)
