Reaction Steps

To a solution of dimethylacetylene dicarboxylate (50.0 g, 344.8 mmol) in diethylether (1 L) under argon at 0° C. was added a solution of methylhydrazine (18.52 mL, 344.8 mL) in diethylether (100 mL) and the resulting mixture stirred for 2 h. The precipitate was filtered off, dissolved in ethanol (300 mL) at 50° C. and then the solution cooled to −20° C. whereupon the solid was filtered off and dried to afford the title compound (46.8 g, 72%) as a light yellow solid. MS: m/e=189.3 [M+H]+.
