実験手順

9-chloro-3-isopropylthieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine (300 mg, 1.19 mmol) and N-methylethane-1,2-diamine (0.50 ml, 5.67 mmol) in methanol (10 ml) was placed into a preheated oil bath at 60° C. After stirring for 15 min, the solution was diluted with saturated ammonium chloride and extracted with methylene chloride. The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated under reduced pressure to yield 4-chloro-3-(3-isopropyl-1H-1,2,4-triazol-5-yl)thiophen-2-amine. Method [7] Retention time 1.39 min by HPLC (M+=243 and 245).
