β¦ Synopsis
A new synthesis of thiphenamil hydrochloride, 2-(diethy1aminoethyl)diphenylthioacetate hydrochloride, a direct-acting smooth muscle antispasmodic with no appreciable anticholinergic or muscarinic activity, is described. The synthesis is carried out under mild conditions and is much simpler than any other known method of preparing this drug.
