Procedure

The procedure described above for the synthesis of intermediate 3 was followed, reacting 1-aminonaphthalene (10.0 g, 69.8 mmol) with chloral hydrate (13.9 g, 83.8 mmol) and hydroxylamine hydrochloride (17.5 g, 0.251 mol) in the presence of sodium sulfate (99 g, 0.70 mol). Isonitrosoacetanilide was obtained as a brownish-black solid (7.09 g, 47% yield).
