Procedure
A mixture of 3-[3-chloro-4-(phenethyloxy) phenyl]-1,1-dimethylurea (16.68 g; 0.0523 mol), n-butanol (300 ml) and 50% aqueous sodium hydroxide (50 ml) is refluxed for 1.5 hours, and then poured onto 500 ml crushed ice. The resultant mixture is extracted with ether (2×200 ml). The ether solution is washed with brine, dried over potassium carbonate and cooled in an ice bath. Dry hydrochloric acid gas is bubbled through the solution. The precipitated amine hydrochloride is collected to afford 10.46 g (0.0368 mol) of product, a white solid, m.p. 198°-204° C.
