Reaction Conditions

Reaction Steps

Aqueous dimethylamine (1 L, 33%) was added to a solution of (1-benzhydrylazetidin-3-yl)methanesulfonate (Intermediate 30, 260 g, 0.82 mol) in CH3CN (1 L) and the mixture was refluxed at 100° C. overnight. The mixture was then cooled and the solvent was removed in vacuo. The mixture was partitioned between water (300 mL) and CH2Cl2 (300 mL) and the layers were separated. The aqueous phase was extracted with CH2Cl2 (3×500 mL). The combined organic solutions were dried (Na2SO4) and concentrated in vacuo. Purification by FCC gave the title compound (200 g, 92%) as a brown solid.
