Abstract

PURPOSE: To obtain 6-hydroxy-6-methylnicotinic acid advantageously, by reacting an N-N'-bis(6-methyl-4-oxo-3,4-dihydro-2-pyrrone-3-indenemethyl) alkylenediamide with ammonia.
CONSTITUTION: Preferably 1mol compound shown by the formulaI(R1 and R2 are H, 1W3C alkyl, aryl; n is 2W3), e.g., N,N'-bis (6-methyl-4-oxo-3,4-dihydro-2- pyrrone-3-indenemethyl)ethylenediamine is reacted with 2W4mol ammonia using a solvent such as methoxyethanol in a sealed tube or in an autoclave at 80W 120°C, to give a compound shown by the formula II useful as an intermedate for drugs such as a cephalosporin derivative, etc. from industrially easily obtainable raw materials by one step without using expensive raw materials such as N,N'- dimethylformamide methylacetal, etc.
