Reaction Steps

2-Chloro-4-(1-fluoroethyl)pyrimidine (58 mg, 0.36 mmol) and acetic acid (0.022 mL, 0.38 mmol) were added to an oven-dried flask containing methyl (2S)-3-[4-(3-amino-5-methylphenyl)-1H-pyrazol-1-yl]-2-hydroxypropanoate (100 mg, 0.36 mmol) in dioxane (1.2 mL). The mixture was stirred for 3 hours at 120° C. then cooled to room temperature, diluted with water, and extracted with EtOAc (3×). The combined organic layers were dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (2 to 100% EtOAc/hexanes) to afford methyl (2S)-3-[4-(3-{[4-(1-fluoroethyl)pyrimidin-2-yl]amino}-5-methylphenyl)-1H-pyrazol-1-yl]-2-hydroxypropanoate. MS ESI calcd. for C20H23FN5O3 [M+H]+ 400. found 400.
