| abstract | NEW MATERIAL:The compound of formula I (when R is H, R 1 is 3,4-dichlorobenzyl, 4-methylbenzyl, 4-methoxybenzyl or 3-trifluoromethylbenzyl; and when R is CH 3 , R 1 is 4-chlorobenzyl or 3,4-dichlorobenzyl). n EXAMPLE: 1-(3,4-Dichlorobenzyl)-3,4-dimethyl-5-methoxypyrazole. n USE: An antiallergic agent. n PREPARATION: When R is CH 3 , the objective compound can be prepared by (1) reacting ethyl 2-methylacetoacetate with the corresponding substituted benzylhydrazine compound in a solvent at room temperature in the presence of a mineral acid catalyst, and (2) methylating the resultant compound of formula II. When R is H, the objective compound is obtained by reacting dimethyl 3-oxoglutarate with a substituted benzylhydrazine compound, methylating the resultant compound of formula III, and subjecting the product to the hydrolysis and thermal decarbonation. n COPYRIGHT: (C)1984,JPO&Japio |
