Reaction Steps

2.1 g of (2-phenoxy-5-thiazolyl)-methanol were added to a solution of 2.44 g of (1R,3S) 2,2-dimethyl-3[(dihydro-2-oxo-3-(2H)-thienylidene)-methyl]-cyclopropane-1-carboxylic acid chloride [described in French Pat. No. 70-21682] in 50 ml of benzene and 3 ml of pyridine were added thereto dropwise at 0° C. The mixture was stirred at 20° C. for 24 hours and was then poured into aqueous 2N hydrochloric acid solution. The decanted organic phase was dried and evaporated to dryness under reduced pressure. The residue was chromatographed over silica gel and was eluted with benzene. The product was crystallized from ethyl acetate to obtain 1.8 g of (2-phenoxy-5-thiazolyl)-methyl (1R,3S) 2,2-dimethyl-3-[(dihydro-2-oxo-3-(2H)-thienylidene)-methyl]-cyclopropane-1-carboxylate.
