Reaction Steps
Solutions of sodium acetate (43.7 g, 0.53 mol) in water (100 mL) and hydroxylamine hydrochloride (37 g, 0.53 mol) in water (100 mL) were added to 7-ethyl-α-oxo-1H-indole-3-acetic acid ethyl ester 4 (17.4 g, 0.07 mol), in ethanol (250 mL) and the mixture was heated at reflux for 12 hours. The ethanol was removed by distillation and the resultant precipitate was filtered and recrystallized from hot ethanol to give the product (13.8 g, 75%), m.p. 167°-169° C. as a mixture of isomers.
