Reaction Steps
7′-Methyl-1-(2,2,2-trifluoroacetyl)spiro[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine]-1′-carbonitrile (250 mg, 0.666 mmol), 1-bromopyrrolidine-2,5-dione (119 mg, 0.666 mmol) and 2-(1-cyano-1-methyl-ethyl)azo-2-methyl-propanenitrile (10.9 mg, 0.0666 mmol) were combined in carbon tetrachloride and the mixture was heated at 80° C. for 4 hours. The mixture was concentrated under reduced pressure and the residue was purified by column chromatography to give 7′-(bromomethyl)-1-(2,2,2-trifluoroacetyl)spiro[piperidine-4,4′-pyrrolo[2,1-c][1,4]benzoxazine]-1′-carbonitrile (53.2 mg, 18%).
