실험 절차

To a stirring mixture of 8-chlorothieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine (60 mg, 0.285 mmol) in MeOH (10 mL) was added N-methylethyl 1,2-diamine (106 mg, 1.4 mmol). The resulting mixture was warmed to 60° C. for 1 hr. The reaction mixture was cooled to rt and then diluted with DCM. This mixture was then washed several times with a saturated NH4Cl solution. The organic layer was dried over MgSO4, filtered, and concentrated under reduced pressure to give 5-chloro-3-(4H-1,2,4-triazol-3-yl)thiophen-2-amine. This amine was taken directly to the next coupling reaction without further purification. Retention time (min)=1.227, method [1], MS (ESI) 201.1 (M+H).
