Then, 15b (0.35 g, 1.72 mmol) dissolved in5 mL of tetrahydrofuran was added. Stirring was continued for an additional1 h in the ice bath (monitored by TLC). The organic phase wasfiltered and the diethyl ether (10 mL) was added to the filtrate. Finally,the solid was precipitated from the filtrate to afford the intermediates16i-k. 4.1.6.1. 2-bromo-N-(1H-pyrazol-4-yl)acetamide (16i).
