A stirred mixture of N-(4-acetylphenyl)formamide (4.9 g) in dimethylformamide (50 mL) under argon was treated with 55% sodium hydride (1.31 g), stireed for 15 minutes and treated with 2-(2-naphthalenyloxy)ethyl methanesulfonate (7.6 g). The mixture was heated at 60° C. overnight and worked upas in Example 20. The material from dichloromethane extraction was purified by HPLC (dichloromethane-ethyl acetate; 20:1 ) and crystallized from dichloromethane-hexane to provide 5.9 g of N-(4-acetylphenyl)-N[2-(2-naphthalenyloxy)ethyl]formamide as a colorless solid, mp 115°-116° C.
