A solution of 105 g (0.68 mole) of 1-cyclohexyl-3-azetidinol and 106 g (0.68 mole) of 2-chloronicotinic acid in 400 ml of dry dimethylformamide was added at a rapid drop to 52 g (1.35 mole) of 60% sodium hydride/mineral oil suspended in 400 ml of dry dimethylformamide at 60° C. Mild exothermic reaction was noted. After stirring for 2 hr at 60° C., the mixture was filtered. The filter cake was washed with ethylacetate and dried at 80° C./2 mm to give 174 g (86%) of crude title compound.
