Reaction Steps

2-amino-3-methoxybenzoic acid 97 (1 g, 6.0 mmol) and pyridine (0.97 mL, 12.0 mmol) were dissolved in dry dichloromethane (30 mL). The resulting mixture was cooled and Troc—Cl (0.9 mL, 6.6 mmol) was added drop wise. The reaction mixture was allowed to stir overnight at room temperature, then washed with HCl (1N, 50 mL), water (50 mL) and brine (50 mL). The organic phase was dried over MgSO4 and evaporated to yield 1.42 g of crude product, which was used in the next step without further purification.
