실험 절차

2-(2-Bromoacetamido)-N-(2-hydroxyethyl)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (1.66 g, 4.60 mmol), 3-tert-butyl-1H-pyrazole-4-carbaldehyde (1.75 g, 11.49 mmol) and potassium carbonate (2.54 g, 18.38 mmol) were mixed with DMF (20 mL) and heated at 70° C. for 2 h. On cooling, the reaction was partitioned between EtOAc and water. The organics were washed with brine, dried over MgSO4 and concentrated directly onto silica for chromatographic purification (0-100% EtOAc/heptane). Concentration in vacuo yielded a white solid (1.64 g, 3.79 mmol, 83%).
