Reaction Steps

To a stirred solution 4-iodo-1H-pyrazole (1.5 g, 7.7 mmol) in DMF (15 ml) was added potassium carbonate (3.2 g, 23.2 mmol) followed by drop wise addition of 2-fluoro benzyl bromide (2.56 g, 8.5 mmol) and stirred the reaction at RT for 15 h. The reaction was monitored by TLC (50% ethyl acetate in hexane). The reaction mixture was diluted with ice water (150 ml) and extracted with ethyl acetate (2×50 ml). The organic layer was dried over Na2SO4, and concentrated under reduced pressure to afford 2.25 g (96.56% yield) of 1-(2-fluorobenzyl)-4-iodo-1H-pyrazole.
