Reaction Steps

2.70 Grams of a potassium salt of 4-(6-chloro-2-benzoxazolyloxy)phenol and 2.48 g of 1-cyano-1-(2,4-dichlorophenyl)-3-chloro-2-butanone were refluxed in 50 ml of N,N-dimethylformamide under heat at 100° C. for 4 hours. The reaction mixture was added to water, and after the mixture was subjected to extraction with chloroform, the extract was concentrated. The residue was separated and purified by column chromatography to give 2.05 g of a compound No. 176 which was a light yellow solid (melting point 93°-94° C.). The yield was 46.9%. The compound No. 176 was analyzed, and the results are shown in Tables 1 to 23.
