Procedure

A stirred solution of methyl 5-{[6-(4-cyanophenyl)-5-(cyclopropylcarbonyl)-4-methyl-2-oxo-3-[3-(trifluoromethyl)phenyl]-3,6-dihydropyrimidin-1(2H)-yl]methyl}-2-furoate (Example 42) (50 mg, 0.09 mmol) in tetrahydrofuran (1.5 ml) is treated with a solution of lithium hydroxide (2.34 mg, 0.1 mmol) in water (1.5 ml). After three hours stirring at room temperature, additional lithium hydroxide (2.34 mg, 0.1 mmol) is added. The reaction solution is stirred overnight (16 h), then allowed to stand for 48 h. The solution is acidified with 1 N hydrochloric acid (500 μl). After 5 minutes stirring, a precipitate is obtained. Methanol (3 ml) is added, and the crude reaction solution is purified directly by preparative HPLC (RP18 column; eluent: acetonitrile/water 30:70→90:10). The title compound is isolated as a brownish solid.
