To a solution 3-[4-(4-chlorophenyl)-2-oxazolyl]propanol (0.5 g) in pyridine (5 ml) was added acetic anhydride (1.0 ml), followed by stirring for 30 minutes at 50° to 60° C. The reaction mixture was poured into water. The precipitated crystals were collected by filtration to obtain 3-[4-(4-chlorophenyl)-2-oxazolyl]propyl acetate (0.535 g, 91%). Recrystallization from ether-hexane gave colorless prism crystals of mp 37°-37.5° C.
