実験手順

A 17.2 g portion of 4-cyano-2-picoline [E. Ochiai and I. Suzuki, Pharm. Bull. (Japan), 2, 147 (1954)] was dissolved in 150 ml of methanol, 756 mg of sodium methoxide was added and the mixture was stirred overnight. A 7.9 g portion of ammonium chloride was added and the mixture was heated to reflux, then cooled to room temperature, giving 15 g of the desired compound, mp 168°-178° C.
