The oil is chromatographed on 200 g of silica gel using a 1:1 (by volume) mixture of ethyl acetate cyclohexane; 25 ml fractions are collected. Fractions 11-14 are combined, mixed with chloroform, evaporated and triturated with ether to give 0.337 g of 11-chloro-8,12b-dihydro-2,8-dimethyl-12b-phenyl-4H-[1,3]oxazino[3,2-d] [1.4] benzodiazepine-4,7(6H)-dione as a pale yellow solid, MP 174°C to 176°C.
