Reaction Steps

N-acylation of an amine of Structure 25 to an amide of Structure 26 Benzenesulfonyl chloride (5 μL, 0.04 mmol) was added under N2 to trans-N-(8-amino-7-chloro-2,3,4,14b-tetrahydro-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)-2,2,2,-trifluoroacetamide (5.0 mg, 0.01 mmol) in a mixture of 1 mL of CH2Cl2 and 25 μL of triethylamine. The resulting mixture was stirred at 40° C. for 4 h. After cooling the mixture was evaporated and the crude compound was purified by chromatography on silica. Elution with toluene/ethyl acetate 1:0→0:1 (gradient) gave trans-N-(7-chloro-2,3,4,14b-tetrahydro-8-[bis(phenylsulfonyl)amino]-1H-dibenzo[b,f]pyrido[1,2-d][1,4]oxazepin-1-yl)-2,2,2-trifluoroacetamide (7.3 mg, 83%). Data: (m/z)=692 (M+H)+.
