The rac-cis/trans benzyl 5-((tert-butoxycarbonyl)amino)-2-methylpiperidine-1-carboxylate (44 g) was separated by chiral SFC to give rac-cis -(2S,5R)-benzyl 5-((tert-butoxycarbonyl)amino)-2-methylpiperidine-1-carboxylate (Peak 2, 24.5 g, 55.68%) and rac-trans - (2S,5S)-benzyl 5-((tert-butoxycarbonyl)amino)-2-methylpiperidine-1-carboxylate_(Peak 1, 12.3 g, 27.95%). Peak 2, cis material was
