Reaction Steps

A mixed solution of cyclopropanecarboxamidine hydrochloride (0.30 g), ethyl cyanoacetate (0.27 ml) and methanol (1.5 ml) was added to 28% sodium methoxide methanol solution (2.0 ml) under ice-cooling. After heating under reflux for 1 hr, the mixture was cooled to room temperature. The reaction mixture was concentrated under reduced pressure, and the obtained residue was adjusted to pH 5 with water and acetic acid. The precipitated solid was collected by filtration, washed with water and dried to give the title compound (0.30 g).
