実験手順

To 1-benzhydryl-azetidin-3-one (1.0 g, 4.2 mmol) in ether (100 mL) at 0° C. was added CH3MgBr (1.5 mL, 3M in ether). The mixture was warmed to rt over 1 h and 1N NaOH (3 mL) was added. The organic layer was concentrated providing the title compound (1.1 g). MS (ESI): mass calcd. for C17H19NO, 253.2; m/z found, 254.2 [M+H]+. 1H NMR (CDCl3): 7.42-7.11 (m, 10H), 4.32 (s, 1H), 3.14 (d, J=8.5 Hz, 2H), 2.96 (d, J=8.5 Hz, 2H), 1.43 (s, 3H).
