To a suspension of 5-bromo-2-chlorobenzoic acid (5.00 g) in dichloromethane (25 ml) at 0° C. was added oxalyl chloride (3.7 ml) and DMF (5 drops). The resulting mixture was stirred at room temperature under a nitrogen atmosphere for 1 h, then concentrated under reduced pressure to yield a solid. The solid was dissolved in dichloromethane (20 ml) and added dropwise to a solution of 1-adamantanemethylamine (3.36 g) and N,N-diisopropylethylamine (5.55 ml) in dichloromethane (20 ml). The resulting solution was allowed to stir at room temperature under a nitrogen atmosphere for 20 h. The reaction mixture was diluted with dichloromethane and washed in sequence with water, 10% aqueous potassium carbonate solution, 10% aqueous potassium hydrogen sulfate and saturated brine. The organiuc phase was then dried over sodium sulfate, filtered and concentrated under reduced pressure to afford the subtitled compound as a solid (7.84 g).
