A mixture of ammonia (7.0 N in methanol, 4 mL) and methyl 2-(4-((2-cyclopentyl-6-ethylpyrimidin-4-yl)methyl)phenyl)acetate (0.067 g, 0.20 mmol) and heated at 100° C. for 48 h. After this time, the mixture was cooled and filtered through celite with ethyl acetate washings. The filtrate was washed with brine (3×15 mL), dried over sodium sulfate, filtered, and concentrated. The residue was purified by column chromatography (silica, hexanes/ethyl acetate) to afford the title compound (0.039 g, 59%) as a white solid.
