실험 절차

(S)-tert-butyl 2-((tert-butyldimethylsilyloxy)methyl)aziridine-1-carboxylate (5.0 g, 17.4 mmol), phenol (4.92 g, 52.3 mmol), K2CO3 (24 g, 174 mmol) and 150 mL of acetonenitrile were mixed, and heated to reflux for 48 h. The mixture was filtrated, and the filtrate was concentrated in vacuo. The residue was dissolved in 100 mL of EA, which was washed with water (50 mL×2), brine (50 mL) and dried with Na2SO4. The solution was concentrated in vacuo to give crude product, which was purified with flash column to give (S)-tert-butyl 1-(tert-butyldimethylsilyloxy)-3-phenoxypropan-2-ylcarbamate (2.0 g, 5.2 mmol, yield 30%) 1H NMR (CDCl3, 400 MHz) δ 0.0 (s, 6H), 0.87 (s, 9H), 1.45 (s, 9H), 3.71 (dd, 1H), 3.85 (dd, 1H), 3.98 (d, 2H), 4.05 (s, 1H), 6.93 (m, 3H), 7.28 (m, 2H). MS ESI +ve m/z 382 (M+1).
