Reaction Steps

A solution of 1.05 g of (2-formyl-phenyl)-N-methoxycarbamic acid methyl ester and 1.05 g of 1-(4-fluorophenyl)-2-hydrazono-propan-1-on-O-methyl-oxime in 5 ml of methanol is stirred at room temperature for 4 hours. The resulting by-product (symmetric azine of 1-(4-fluorophenyl)-2-hydrazono-propan-1-on-O-methyl-oxime) is removed by filtration and the filtrate is placed in a refrigerator over night. The product which has crystallised is filtered off (1.0 g). By concentrating the mother liquor and by means of fractional crystallisation of the residue, a further 0.48 g of the title compound are obtained in the form of yellow crystals having a melting point of 88-90° C.
