Hydrochloric Acid → 4-(3,4-Dichloro-phenyl)-5-(2,2,2-trifluoro-ethoxy)-pyrimidine-2-carboxylic acid

Participants

Reaction Steps

To a solution of 3.79 g 4-(3,4-dichloro-phenyl)-5-(2,2,2-trifluoro-ethoxy)-pyrimidine-2-carboxylic acid methyl ester in 28 mL tetrahydrofuran was added 13 mL of a 1M solution of lithium hydroxide in water and the mixture was stirred at room temperature for 1 h. The reaction mixture was acidified by addition of 1M hydrochloric acid. The precipitate was collected by filtration washed with water and dried to constant weight under high vacuum to yield 3.561 g (97.55%) of the title compound as white solid, MS 365.0 (M−H)−.
