Reaction Steps

Add methylamine (1120 mL, 2.6 Eq.) to 2-(1-ethoxy-ethylidene)-malononitrile (115 g, 0.84 mol) in ether dropwise while stirring at room temperature under a nitrogen atmosphere. Stir at this temperature for 2 hours and then concentrate under reduced vacuum. Triturate the resulting solid in ethyl acetate (400 mL) and filter to produce 102 g of the title compound as a tan solid. Mass spectrum (m/e): 122.0 (M*+1): (Bruker 300)
