Procedure
A mixture of 4-(3-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (8.00 g), N-hydroxyphthalimide (4.13 g), potassium carbonate (7.05 g) and N,N-dimethylformamide (80 ml) was stirred at room temperature for 20 hours and water (800 ml) was added. The resultant crystals were filtered and washed with water to obtain N-[3-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzyloxy]phthalimide (10.1 g, yield 90%) as pale-brown crystals. m.p. 146-147° C.
