Procedure

Iodomethane (36 mg, 0.255 mmol) and K2CO3 (44 mg, 0.319 mmol) were added to a solution of N-(4-chloro-3-(1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(5-oxopyrazolo[1,5-a]pyrimidin-4(5H)-yl)acetamide (80 mg, 0.212 mmol) in DMF (1 mL). The reaction mixture was stirred at room temperature for 30 minutes and was subsequently diluted with ethyl acetate and washed with brine. The organic phase was dried (Na2SO4), filtered, concentrated under vacuum and purified by preparative HPLC to give N-(4-chloro-3-(1-methyl-1H-1,2,4-triazol-3-yl)thiophen-2-yl)-2-(5-oxopyrazolo[1,5-a]pyrimidin-4(5H)-yl)acetamide. Retention time (min)=3.00, method [7], MS (ESI) 390.1 (M+H); 1H NMR (300 MHz, CD3C1) δ 8.25 (d, J=8.2 Hz, 1H), 7.90 (s, 1H), 7.76 (d, J=2.1 Hz, 1H), 6.79 (s, 1H), 6.22 (d, J=8.2 Hz, 1H), 5.97 (d, J=2.1 Hz, 1H), 5.36 (s, 2H), 3.99 (s, 3H).
