实验步骤: A mixture of 3.24 grams of 2-methoxy-3-naphthonitrile, 2.23 grams of cyanoguanidine and 0.24 gram of KOH was dissolved in 30 ml of methyl cellosolve with heating and the mixture was heated to reflux for 6.5 hours. After the reaction was completed, the reaction solution was was poured into water, the crystals separated out were taken by filtration, and were recrystallized from ethyl alcohol to give 2,4-diamino-6-(2-methoxy-3-naphthyl)-s-triazine, colourless needles, melting point 243° to 244° C., the yield being 4.12 grams. with heating the mixture was heated to reflux for 6.5 hours the crystals separated out were taken by filtration were recrystallized from ethyl alcohol
