Participants

Reaction Steps

To a solution of 6-[(4-tert-butylphenyl)sulfonyl]-2-(trifluoromethyl)-6,11-dihydro-5H-pyrido[2,3-b][1,5]benzodiazepine-8-carbonitrile (0.60 g, 1.23 mmol, intermediate 54) in ethanol (6 mL) at rt was added hydroxylamine (0.24 mL of a 50% aqueous solution), and potassium carbonate (0.02 mL of a 0.8 M aqueous solution). After stirring at rt for 45 min, the reaction mixture was heated at 105° C. for 65 min in a microwave reactor. After cooling to rt, the precipitate was collected by filtration to provide the title compound. LC/MS: m/e 520.2 (M+H)+.
