Reaction Steps

Prepared by chiral preparative HPLC separation of racemic 7-(2-methyl-1H-benzimidazol-6-yl)-4-[(2-phenylpiperidin-1-yl)carbonyl]-2,3,4,5-tetrahydro-1,4-benzoxazepine (example 1) using a SHIMADZU LC-20AD apparatus equipped with a Chiralpak AD-H, 25 cm×4.6 mm column using a mobile phase of ethanol:methanol 1:1 and flow rate of 18.0 mL/min and detection at 220 nm. The isomer with retention time 11.20 min. was assigned as the (R)-enantiomer. Chiral analytical HPLC was carried out using a SHIMADZU LC-20AD apparatus equipped with a Chiralpak AD-H, 25 cm×4.6 mm column using a mobile phase of ethanol:methanol 1:1 and flow rate of 0.7 mL/min with detection at 254/220 nm. This isomer gave a retention time 9.51 min and ee>99%. MS (EI) C29H30N4O2: 467 (MH+).
