(R)-1-(3-tert-butyloxycarbonylphenyl)-ethyl methanesulfonyl ether (3.28 mmol) was dissolved in N,N-dimethylformamide (20 mL) and sodium azide (8.57 mmol) was added. The resultant mixture was heated to 60° C. for 45 min then stirred at room temperature overnight. Worked up by pouring into water and extracting 3× with diethyl ether. The combined organic extracts were washed with brine, dried (MgSO4) and concentrated under reduced pressure to yield 769 mg of an oil which was used without further purification. 1H NMR (500 MHz, CDCl3): δ 7.96 (m, 2H); 7.52 (m, 1H); 7.45 (m, 1H); 4.69 (q, J=6.9 Hz, 1H): 1.63 (s, 9H); 1.57 (d, J=6.8 Hz, 3H).
