실험 절차

To a stirring mixture of thieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine (123 mg, 0.7 mmol) in HOAc (1 mL) was added NCS (200 mg, 1.5 mmol), Pd(OAc)2 (48 mg, 0.21 mmol). The reaction mixture was stirred at 120° C. overnight. The reaction was neutralized with a saturated NaHCO3 solution and extracted with DCM. This product was purified via an isco column to give 8-chlorothieno[3,2-e][1,2,4]triazolo[4,3-c]pyrimidine as the major product. Retention time (min)=1.663, method [1], MS (ESI) 211.0 (M+H).
