実験手順

To a room temperature solution of 750 mg of trans-3-(2-bromoethyl)-7-chloro-5-cyclopropylethenyl-1,5-dihydro-1-(4-methoxybenzyl)-5-(trifluoromethyl)-4,1-benzoxazepin-2(3H)-one in 35 mL of acetonitrile was added 18 mL of water and 3.78 g of ceric ammonium nitrate. After 20 min, the reaction mixture was partitioned between eater and ether, and the organic layer was washed with aqueous bicarbonate and brine, dried and evaporated. This produced two diastereomeric products which were separated by column chromatography over silica gel (elution with 10-25% ethyl acetate in hexanes). The first diastereomer eluted (162 mg) was the title compound.
