Procedure
In 175 ml of DMF containing 138 g of anhydrous potassium carbonate (1.0 m) was added 100 g of 3-hydroxy-4-methoxybenzaldehyde and 127 g of cyclohexylmethybromide. The mixture was heated at reflux temperature overnight and then poured into cold water and extracted with ethyl acetate. The extracts were dried and evaporated in vacuo to render the desired subtitled intermediate, b.p. 130°-135 ° C.
