To a solution of 14.0 g (0.105 mol) of 3-hydroxyphenylacetonitrile in 500 ml of acetone were added 25.9 g (0.105 mol) of 4-chloromethyl-2-phenylthiazole hydrochloride and 34.2 g (0.105 mol) of cesium carbonate and 1 g of potassium iodide and the slurry is heated to reflux for 20 hours. The mixture is filtered and the solution is concentrated in vacuo to obtain crystals. Recrystallization from ethyl acetate gives 14.0 g (43%) crystals, m.p. 108°-110° C. The product is used without further purification in subsequent reactions.
