실험 절차

A boiling solution of 20.0 grams of 4-bromobenzaldehyde in 250 milliliters of ethanol is stirred vigorously as a solution of 6.1 grams of 1,2-diaminoguanidine nitrate and 0.5 milliliters of concentrated nitric acid in 50 milliliters of water is added in one portion. The reaction mixture is stirred as the temperature recedes to room temperature. The reaction mixture is allowed to stand for several hours. The precipitate which forms is collected, washed with hot ethanol, air dried and finally dried at 60° C. under reduced pressure. The yield is 16.5 grams of product and the melting point is 178°-180° C. with decomposition.
