实验步骤: R-(−)-Mandelic acid (2.26 kg) was added to a solution containing trans-(1R,2S)-2-(3,4-difluorophenyl)cyclopropylamine (2.6 kg, 91.8% enantiomeric excess), stirring at 17° C. in ethyl acetate (45.3 L). The mixture was stirred at 25° C. for 3 hours and 8 minutes, then filtered and washed twice with ethyl acetate (13.8 kg total). The crystalline product was dried at 40° C. under reduced pressure for 23 hours, affording trans-(1R,2S)-2-(3,4-difluorophenyl)cyclopropanaminium (2R)-2-hydroxy-2-phenylethanoate (4.45 kg). filtered washed twice with ethyl acetate (13.8 kg total) The crystalline product was dried at 40° C. under reduced pressure for 23 hours
