Reaction Steps

A solution of diketone (87) (200 mg, 0.43 mmol) and hydroxylamine hydrochloride (60 mg, 0.86 mmol) in EtOH (5 mL) was irradiated in a microwave reactor (Biotage) for 20 min. at 140° C. Purification by Prep-LC (Gilson) provided 67 mg (34%) of 5-t-butylisoxazole and 28 mg (14%) of 3-t-butylisoxazole as solid.
