Procedure

2 g of (2-phenoxy-5-thiazolyl)-methanol were added to a solution of (1R,3R)2,2-dimethyl-3-[(dihydro-2-oxo-3-(2H)-thienylidene)-methyl]-cyclopropane-1-carboxylic acid chloride [described in French Pat. No. 70-21682 published under No. 2.097.244] prepared from 2.2 g of the corresponding acid in 30 ml of benzene and 0.81 ml of pyridine were added thereto at -10° C.The reaction mixture was stirred at 20° C. for 17 hours and was poured into aqueous dilute hydrochloric acid. The decanted aqueous phase was extracted with ether and the combined organic phases were washed with water, dried and evaporated to dryness under reduced pressure. The residuewas chromatographed over silica gel and was eluted with an 8-2 cyclohexane-ethyl acetate mixture to obtain 2.9 g of (2-phenoxy-5-thiazolyl)-methyl (1R,3R) 2,2-dimethyl-3[(dihydro-2-oxo-3-(2H)-thienylidene)-methyl]-cyclopropane-1-carboxylate.
