実験手順

9-Chloro-3-ethylthieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine (20 mg, 83.8 umol) and N-methylethane-1,2-diamine (0.05 ml, 5.67 umol) in methanol (2 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 afford 18 mg (94% yield) of 4-chloro-3-(3-ethyl-1H-1,2,4-triazol-5-yl)thiophen-2-amine as a brown solid. Method [8] Retention time 2.63 min by HPLC (M+ 229 and 231).
