2-Fluoroethyl bromide → HCID 18326216, compound

Participants

Reaction Steps

1.0 g (0.0027 mol) of N-(2-mercaptoethyl)-4-methoxy-6-{3-(trifluoromethyl)phenoxy}-2-pyridine carboxamide (compound No. I-91) was dissolved in DMF, and the obtained solution was mixed with 0.12 g (ca. 60% in mineral oil; 0.0027×1.1 mol) of NaH and then with 0.68 g (0.0027×2.0 mol) of 1-bromo-2-fluoroethane, followed by stirring the solution for about one hour. The reaction solution was distributed in ethyl acetate-saturated sodium bicarbonate water and then washed with saturated brine. The organic phase of the solution was dried with anhydrous sodium sulfate, concentrated and purified by silica gel column chromatography (eluting solution: ethyl acetate/hexane), thereby obtaining an aimed product.
