Procedure

A solution of (S)-3-(2-chloropyrimidin-4-yl)-5,5-dimethyl-4-phenyloxazolidin-2-one (33.9 mg, 0.112 mmol) and (S)-(−)-1-phenylethanamine (0.15 mL, 1.2 mmol, 10 equiv) in DMSO (1 mL) was heated at 110° C. for 140 min. 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 50%) provided (S)-5,5-dimethyl-4-phenyl-3-(2-((S)-1-phenylethylamino)pyrimidin-4-yl) oxazolidin-2-one (37.0 mg, white solid) in 85% yield. 1H NMR (400 MHz, CD3OD) δ 8.06 (d, J=5.8 Hz, 1H), 7.43 (d, J=5.8 Hz, 1H), 7.31-7.24 (m, 3H), 7.19-7.11 (m, 5H), 7.01 (br s 2H), 5.48 (s, 1H), 4.86-4.80 (m, 1H), 1.65 (s, 3H), 1.43 (d, J=7.0 Hz, 3H), 0.98 (s, 3H); HRMS(B) m/z 389.1987 (M+H)+.
