Participants

Reaction Steps

A stirred solution of (18(b)) (3.85 g, 11.4 mmol) in MeOH (100 mL) at room temperature under argon was treated with 2N NaOH (12 mL, 24 mmol). The reaction mixture was allowed to stir at room temperature for 4 h. concentrated to 1/5 volume and acidified to pH4 with 2N HCl. The resulting precipitate was then collected by filtration. washed with water (2×25 mL) and dried under high vacuum to yield 3-(3,4-dichlorobenzyl-carbamoyl)-benzoic acid (18(c)) as a white powder: 2.9 g (79%).
