To a solution of 3-(methyloxiran-2-yl)methanol (0.826 g, 9.38 mmol) in DCM was added α-aminodiphenylmethane (1.50 mL, 8.44 mmol) and titanium(IV) isopropoxide (5.5 mL, 18.7 mmol), and the reaction mixture was heated at 60° C. for 16 h. A saturated aqueous solution of Rochelle's salt was added to the mixture followed by a solution of 3 N NaOH. The reaction miture was stirred overnight. The aqueous phase was then extracted with DCM (3×). The combined organic layers were washed with brine, dried with sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified via FCC (30-60% EtOAc/heptanes) to give the title compound. MS (ESI+) m/z 272.4 (M+H)+.
