Versuchsvorschrift

A solution of (±)-2-(2-naphthylmethoxy)-3,3,3-trifluoro-2-methylpropionyl chloride (1.3 g.) in ether (10 ml.) is added to a mixture of ammonia (d, 0.90; 10 ml.) and water (100 ml.). The mixture is shaken, and the ether is evaporated. The solid is filtered off and crystallised from light petroleum (b.p. 100°-120° C.) to give (±)-2-(2-naphthylmethoxy)-3,3,3-trifluoro-2-methylpropionamide (0.76 g.) m.p. 111°-112° C.
