Procedure

To a solution of methyl 2-(2-(2-chlorophenyl)-4-methyl-6-p-tolylpyrimidin-5-yl)pentanoate (27 mg; 0.066 mmol) in methanol (660 μL) was added a 10 N sodium hydroxide solution (66 μL; 0.66 mmol) and the mixture was heated at 100° C. for 18 h. The volatiles were removed under reduced pressure and the mixture was acidified by adding 6N hydrochloric acid. The suspension was extracted twice with ethyl acetate. The combined organic layers were washed with a saturated sodium chloride solution, dried over magnesium sulphate and concentrated under reduced pressure to give 19 mg (72%) of the title compound as a white solid. ESI/APCI(+): 395 (M+H).
