2-Bromomethylnaphthalene was reacted with ethyl vanillate using the conditions described in Example 1 to give ethyl 3-methoxy-4-(naphth-2-ylmethoxy)benzoate in 54% yield, m.p. 86°-87° C. Following the procedures described in the portion of Example 6 which is concerned with the preparation of starting materials the product so obtained was reacted with thiazol-2-yl-lithium and the resultant product was reacted with ethylmagnesium iodide to give the required starting material as an oil in 20% yield, m.p. 124°-126° C. (recrystallised from a mixture of hexane and ethyl acetate).
