To a room temperature solution of 1.13 g of 3-(2-bromoethyl)-7-chloro-5-cyclopropylethynyl-1,5-dihydro-1-(4-methoxybenzyl)-5-(trifluoromethyl)-4,1-benzoxazepin-2(3H)-one in 50 mL of acetonitrile was added 25 mL of water and 5.7 g of ceric ammonium nitrate. After 30 min, the reaction mixture was partitioned between water 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 (270 mg) was the title compound.
