반응 단계
Racemic [5-(5-amino-2-fluoro-phenyl)-5-difluoromethyl-2,5,6,7-tetrahydro-[1,4]oxazepin-3-yl]-carbamic acid tert-butyl ester (1.62 g, 4.04 mmol) was separated via a VWR prep HPLC System on a Chiralpak AD 20 um 4×50×100 (4×SMB columns) column; eluent: heptane/ethanol 70/30; flow=65 ml/min; UV detection at 220 nm. As a result, 754 mg of the desired title compound ((S)-isomer) was obtained as the first eluting isomer. Purity: >99.5% ee.
