Reaction Steps
A solution of 2.80 g of 5-{7-[4-(4,5-dihydro-2-oxazolyl)phenoxy]heptyl}-3-isoxazolemethanol (Example 11) and 0.82 g of acetic anhydride in pyridine was allowed to stand overnight at room temperature. The reaction mixture was poured into ice water and the solid material which formed was collected, dried and recrystallized from isopropyl alcohol to give 2.5 g of 5-{7-[4-(4,5-dihydro-2-oxazolyl)phenoxy]heptyl}-3-isoxazolemethanol acetate, colorless solid, m.p. 76°-77° C.
