IR 2243, 1540 cm-1. MS 418 (MH+), 243. Anal. calcd. for C30H27NO: C, 86.30; H, 6.52; N, 3.35. Found: C, 86.07; H, 6.39; N, 3.24. To a solution of trimethyl aluminum (1M in hexanes, 0.57 mL), in toluene (3 mL) at ~2° C., was added azidotrimethylsilane (0.569 mmol). A solution of nitrile (0.474 mmol) in toluene (2 mL) was slowly added. The reaction was stirred at 80° C. for 72 h. The cooled (0° C.) reaction was added dropwise to HCl (6M, 10 mL) and EtOAc (10 mL). The resulting mixture was extracted with EtOAc (2×50 mL). The combined organic layers were dried (MgSO4), filtered and evaporated. The crude material was triturated with dichloromethane to remove unreacted starting nitrile leaving behind the title compound as a hydrate, a white solid (mp=193°-195° C., 30% yield). 1H NMR (DMSO-d6) δ 7.19-7.35 (m, 15H), 7.02 (d, J=8.5 Hz, 2H), 6.58 (d, J=8.5 Hz, 2H), 3.60 (t, J=7.4 Hz, 2H), 3.04-3.12 (m, 4H), 2.91 (t, J=7.6 Hz, 2H).
