Abstract

NEW MATERIAL:A pyrazolecarboxylic acid derivative expressed by formula I [R1 is straight chain alkyl of CnH2n+1 (n is an integer 13W17); R2 is H or lower alkyl].
EXAMPLE: Ethyl5-n-tridecylpyrazole-3-carboxylate.
USE: A medicine having remarkably improved antilipemic action.
PROCESS: An enolate sodium salt of formula II obtained by the Claisen condensation of a higher alkyl methyl ketone with diethyl oxalate is heated with hydrazine hydrate in a mineral acid under refluxing for 4W10hr with stirring to give an ester compound of formula I, which is then reacted with NaOH in an aqueous solution of a lower alkanol at 100°C to give the compound of formula I.
