Reaction Conditions

Reaction Steps

305 mg (1.07 mmol) of 3-[4-(3-fluoro-benzyloxy)-phenyl]-2-methyl-acrylic acid is dissolved in 8 ml of dichloromethane and one drop of dimethylformamide is added. The solution is cooled to 0° C. and treated dropwise with 676 mg (5.33 mmol) oxalyl chloride. The resulting solution is stirred at 0° C. for additional 30 minutes, then 2 hours at RT. Evaporation of the solvent leaves the crude acid chloride which is dissolved in 5 ml THF. This solution is slowly added under stirring to 10 ml of concentrated ammonia. The precipitate is filtered off and recrystallised from methanol to yield 199 mg (65%) of a colorless solid. MS: m/e=286.2 (M++H).
