To a solution of diethyl 1-benzylazetidine-3,3-dicarboxylate (4.8 g, 16.5 mmol) in CH3OH (10 mL) was added NaBH4 (1.25 g, 33 mmol). The mixture was stirred at RT for 1 hr. 100 mL of brine and 200 mL of DCM were added. Organic layers were separated from aqueous layers, dried over Na2SO4, concentrated to afford 2.328 g (68%) of (1-benzylazetidine-3,3-diyl)dimethanol as a yellow oil. 1H NMR (400 MHz, DMSO-d6) δ 7.21-7.31 (m, 5 H), 4.15-4.05 (m, 2 H), 3.48 (d, J=4.8 Hz, 2H), 3.17 (d, J=4.8 Hz, 4 H) and 2.89 (s, 2 H).
