To a solution of (S)-2-((1-adamantylmethyl)amino)-1-phenylethanol (35 mg, 0.12 mmol), Et3N (24.8 mg, 0.25 mmol) in CH2Cl2 (2 mL) at 0° C. was added triphosgene (14.6 mg, 0.05 mmol) and the mixture was stirred for 30 min. The mixture was concentrated under vacuum to give the crude product, which was purified by preparative TLC to give (S)-3-((1-adamantyl)methyl)-5-phenyloxazolidin-2-one (10 mg, 26%). 1H NMR (MeOD, 400 MHZ): δ=1.51-1.95 (m, 15H), 2.89 (q, 2H), 3.55 (q, 1H), 4.10 (t, 1H), 5.57 (q, 1H), 7.34˜7.45 (m, 5H); MS m/z=312.
