Participants

Reaction Steps

A solution of 2-(3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenoxy)-2-methyl-propionic acid ethyl ester [330 mg, 0.7 mmol, Example 22(a)] in a 2M solution of sodium hydroxide (5 mL, 10 mmol) in MeOH (4 mL), THF (2 mL) and water (4 mL) is heated to 60° C. for 30 minutes. After an additional 5 hours at room temperature, the mixture is concentrated, and diluted with water and ethyl acetate. The solution is acidified with dilute hydrochloric acid to pH, 2.0, and extracted with ethyl acetate. The extracts are dried over magnesium sulfate, filtered, and concentrated to afford 2-(3-{2-methoxy-6-[2-(4-methoxy-phenyl)-ethylamino]-pyrimidin-4-yl}-phenoxy)-2-methyl-propionic acid [0.21 g, 72%, Example 23(a)]. LCMS: RT=2.47 minutes, MS: 438 (M+H).
