5.86 gms. of 5-chloro-1,3-dimethyl-1H-dipyrazolo[1,5-a:4',3'-e]pyrazine-6-carboxylic acid, ethyl ester, are refluxed with 2 gms. of sodium bisulfide and 50 ml. of n-propanol for 3 hours. On cooling, the product, 1,3-dimethyl-5-mercapto-1H-dipyrazolo[1,5-a:4',3'-e]pyrazine-6-carboxylic acid, ethyl ester, crystallizes in the form of yellow filamentous needles which are recrystallized from n-propanol, yield 4.76 gms., m.p. 189°-191°.
