Reaction Steps

To a stirred solution of 1,4-dihydro-4-methylcyclopent[b]indol-3(2H)-one (3.0 g) in 30 ml of 95% EtOH was added hydroxylamine hydrochloride (2.25 g) in 9 ml water followed by sodium acetate (4.4 g) in 9 ml water. The mixture was heated at reflux for 4 hours and thereafter an additional 1.1 gram of hydroxylamine hydrochloride in 5 ml water and 2.2 grams of sodium acetate in 5 ml water were added.. After an additional 2 hours of reflux, the mixture was allowed to stand at room temperature overnight. The material which precipitated was collected and recrystallized from 95% EtOH to give 1.9 grams of analytically pure material.
