実験手順

(S)-2-Phenyl-2-tert-butoxycarbonylaminoethyl methanesulfonate (15.77 g, 0.05 mol) was dissolved in 50 mL DMF followed by the addition of sodium azide (19.5 g, 0.3 mol). The mixture was stirred for 24 hrs at 55° C., cooled to room temperature, poured into cold water (500 mL) and stirred vigorously for 20 minutes. Precipitate was collected by filtration, washed with water and dried, affording 9.97 g of the title compound as a white solid. Yield: 76%; (MH)+=263; 1H NMR (DMSO-d6): 1.37 (s, 9H), 3.36-3.50 (m, 2H), 4.69-4.75 (m, 1H), 7.23-7.36 (m, 5H), 7.65-7.68 (d, J=9.2 Hz, 1H).
