To a solution of triphenylphosphine (0.315 g, 1.2 mmol) in tetrahydrofuran (THF, 5.0 mL) was added diethyl azodicarboxylate (0.19 mL, 1.2 mmol) and tert-butyl(S)-2-hydroxypropanoate (292 mg, 2 mmol) followed by 4-(2-aminopyrimidin-5-yl)-2-fluorophenol (0.20 g, 1.0 mmol) at RT (RT) under nitrogen. The mixture was stirred overnight at RT, evaporated and the residue was purified by chromatography on silica gel to afford the desired product (0.24 g, 72%). LCMS: (M+H)=334. 1.
