Briefly, to a solution of l-benzhydrylazetidin-3-one (1.84 g, 7.76 mmol) and (S)-l-(4- (trifluoromethyl)phenyl)ethan- 1 -amine (1.47 g, 7.76 mmol, 1.0 equiv.) in MeOH (10 mL) were added diphenylmethyl isocyanide (1.50 g, 7.76 mmol, 1.0 equiv.) and 2-chloroacetic acid (733 mg, 7.76 mmol, 1.0 equiv.) sequentially. The resulting mixture was stirred at r.t. for 5 h, diluted with EA (150 mL), washed with saturated aqueous NaHC03 (100 mL), saturated aqueous NH4Cl (100 mL) and brine, dried over sodium sulfate, concentrated under reduced pressure, and purified by silica gel chromatography using EA/Hex (1/4) to provide 2.0 g (36%) of (S)-N,l-dibenzhydryl-3-(2-chloro-N-(l-(4-(trifluoromethyl)phenyl) ethyl)acetamido)azetidine-3-carboxamide.

To a mixture of 3-((tert-butyldimethylsilyl)oxy)cyclobutan-l-one (1.0 g, 5.0 mmol) and (4-(trifluoromethyl)phenyl)methanamine (874 mg, 5.0 mmol) in a RB flask was added MeOH (10 mL). The mixture was stirred at r.t. for 5 min. To this mixture were added (isocyanomethylene)dibenzene (965 mg, 5.0 mmol) and 2-chloroacetic acid (472 mg, 5.0 mmol) sequentially. The resulting mixture was stirred at r.t. for 5 h, diluted with EtOAc (150 mL), washed with saturated aqueous NaHC03 (50 mL), saturated aqueous NH4Cl (50 mL), and brine, dried over sodium sulfate, concentration under reduced pressure, and purified by silica chromatography using 20% EA/Hex to provide 1.2 g (1.8 mmol, 36% yield) of the first eluting Diastereomer 46-1A and 698 mg (1.08 mmol, 21% yield) of the second eluting Diastereomer 46- 1B.
