実験手順

0.82 Grams (4.13 millimoles) of 2-aminoacetanilide hydrochloride, 0.77 g (4.13 millimoles) of 2-aminoacetanilide (free base) were dissolved in 1.4 milliliters of hot methanol. To this solution was added 0.76 milliliters (0.67 g, 4.13 millimoles) of triethyl orthoacetate. The mixture was heated gently for five minutes. The reaction mixture was cooled and the reaction product precipitated by addition of diethyl ether. The supernatant liquid was decanted, and the precipitate was triturated with ether and collected on a filter. The product was recrystallized from ethanol, and dried to yield about 300 milligrams of N,N'-bis[phenylcarbamylmethyl]acetamidine hydrochloride.
