trans-7-Chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepine-1-amine (10 mg, 0.03 mmol) was dissolved in 1 mL of ethyl fluoroacetate. The resulting mixture was heated to reflux for 2 h. Evaporation followed by crystallisation from methanol gave trans-N-(7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)-2-fluoroacetamide (4.7 mg, 39%). Data: (m/z)=361 (M+H)+.
