Reaction Steps

102.3 g (0.72 mol) dimethyl acetylenedicarboxylate was added to 1000 ml ether and cooled to -5° C. in an ice-methanol bath. 33 g (0.72 mol) Methylhydrazine in 100 ml ether was added dropwise so that the inner temperature did not rise above 0° C. The mixture was stirred for 1 hour at 0° C., the precipitate filtered off, washed with ether and dried in vacuo at 40° C. The intermediate was immersed for 10 minutes in an oil bath heated to 120° C. The reduction product was recrystallised from methanol.
