Reaction Steps

2-Bromomethylnaphthalene was reacted with 3-hydroxy-4-methoxybenzaldehyde using the conditions described in Example 1 to give 4-methoxy-3-(naphth-2-ylmethoxy)benzaldehyde in 50% yield, m.p. 80° C. Following the procedure described in Note k. above the product so obtained was reacted with thiazol-2-yl-lithium to give 2-[4-methoxy-3-(naphth-2-ylmethoxy)-α-hydroxybenzyl]thiazole as an oil in 62% yield; that product was oxidised with sodium dichromate to give 4-methoxy-3-(naphth-2-ylmethoxy)phenyl 2-thiazolyl ketone in 58% yield, m.p. 149°-150° C.; and the product so obtained was reacted with ethylmagnesium iodide to give the required starting material in 45% yield, m.p. 80° C.
