Participants

Reaction Steps

A solution of (S)-3-(2-chloropyrimidin-4-yl)-4-isopropyloxazolidin-2-one (93 mg, 0.38 mmol), 1-(1-(4-methoxyphenyl)-1H-pyrazol-4-yl)ethanamine hydrochloride (514 mg, 2.03 mmol, 5.3 equiv) and iPr2NEt (0.605 mL, 3.46 mmol, 9.0 equiv) in DMSO (1.5 mL) was heated at 110° C. for 16 h. The reaction mixture was diluted with EtOAc (8 mL) and washed with water (30 mL). After separation, the aqueous phase was extracted with EtOAc (3×8 mL). Combined organics were dried over Na2SO4, filtered and concentrated. Silica gel column chromatography (EtOAc/Heptane 10 to 70%) provided (S)-4-isopropyl-3-(2-((R)-1-(1-(4-methoxyphenyl)-1H-pyrazol-4-yl)ethylamino)pyrimidin-4-yl)oxazolidin-2-one and (S)-4-isopropyl-3-(2-((S)-1-(1-(4-methoxyphenyl)-1H-pyrazol-4-yl)ethylamino)pyrimidin-4-yl)oxazolidin-2-one.
