Reaction Steps

To a solution of 1.2 g of 5-{5-[4-(4,5-dihydro-2-oxazolyl)-2-formylphenoxy]pentyl}-3-methylisoxazole (Example 70) in 10 ml of methanol was added in portions 0.2 g of sodium borohydride. The mixture was stirred for one hour, then treated with a few drops of glacial acetic acid and diluted to 50 ml with water. The solid product was collected, washed with aqueous methanol and recrystallized from ethyl acetate to give 1.2 g of 5-{5-[4-(4,5-dihydro-2-oxazolyl)-2-hydroxymethylphenoxy]pentyl}-3-methylisoxazole, m.p. 140°-141° C.
