Reaktionsschritte

To a solution of 4-bromo-1H-pyrazole (0.1 g, 0.68 mmol) in DMF (20 ml) were added K2CO3 (0.19 g, 1.36 mmol, 2 eq.) and (bromomethyl)cyclopropane (92 mg, 0.68 mmol, 1 eq.). The mixture was stirred at RT for 4 h. The mixture was quenched and extracted as in Intermediate Example 5(c). The solvent was distilled off to afford the crude product (0.15 g).
