Reaction Steps

Hydroxylamine hydrochloride (6 g, 86 mmol) and 3-cyclopentyl-3-oxopropanenitrile (10 g, 73 mmol) were added to a solution of NaOH (9 g, 225 mmol) in water (100 mL) and the resulting mixture was heated at 50° C. overnight. The precipitate was collected by filtration, washed with water, and dried to give 3-cyclopentylisoxazol-5-amine (6.7 g, 61% yield). 1H NMR (400 MHz, DMSO-d6): δ 6.43 (s, 2 H), 4.77 (s, 1 H), 2.84 (m, 1 H), 1.87-1.51 (m, 8 H); MS (ESI) m/z: 153.1 (M+H+).
