実験手順
2-Amino-6-chloro-4-pyrimidinol, monohydrate (85%, 100 g, 0.5197 mol) was suspended in methoxyethanol (700 ml) and 2-thienylmethylamine (96%, 61.3 g, 0.5197 mol) was added to the suspension. The mixture was heated under reflux for two hours and then 73 ml (d=0.726; 0.52 mol) of triethylamine was added and the refluxing continued for an additional 18 hours. The reaction mixture was poured into ice water (1000 ml), acidified with acetic acid (ph 4.0) and the precipitated solid was filtered, washed, and dried. Yield: 110 g (72.6%). This was used in the next step without further purification.
