To a solution of 2.655 g 4-(4-chloro-phenyl)-5-cyclopropylmethoxy-pyrimidine-2-carboxylic acid methyl ester in 27 ml tetrahydrofuran was added 11 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 2.473 g of the title compound as white solid. MS (EI): 305.1 (M+H).
