Reaction Steps

To a stirring solution of methyl 2-aminobenzoate (5 g, 33.1 mmol) and pyridine (5.3 g, 66 mmol) in dichloromethane (100 mL) was added 4-dimethylaminopyridine (0.2 g, 1.6 mmol). The mixture was cooled to 0° C. and treated with 4-tert-butylbenzoyl chloride (6.5 g, 33.1 mmol). After stirring overnight, the reaction mixture was diluted with dichloromethane (100 mL)and washed twice with 1 M aqueous citric acid (100 mL). The organic layer was then washed sequentially with water (100 mL) and 5 N aqueous HCl. It was dried over MgSO4, filtered and concentrated in vacuo to give 10.68 g (quantitative) of a colorless oil.
