Procedure

To a 1.75 g. portion of 1-(3-p-fluorobenzoylpropyl)-4-(2-oxazolyl)pyridinium perchlorate, prepared as described in Example 9, in 75 ml. of methanol, is added portionwise with stirring 1.75 g. of sodium borohydride. The mixture is stirred for 11/2 hours, allowed to stand, some of the methanol is evaporated and the mixture is poured into ice water causing the formation of a tan solid which is recovered by filtration, m.p. 100°-103°C.
