Triethylamine → 4-Cyano-3-fluorobenzyl methanesulfonate

Participants

Reaction Steps

2-Fluoro-4-hydroxymethylbenzonitrile (1.3 g, 8.6 mmol; see step (ii) above) was dissolved in 50 mL of CH2Cl2 and cooled on an ice bath. Triethylamine (0.87 g, 8.6 mmol) and methanesulfonyl chloride (0.99 g, 8.7 mmol) were added. After stirring for 1.5 h the reaction mixture was washed with 1M HCl. The organic phase was dried (Na2SO4) and evaporated. The product could be used without purification. Yield of a colourless oil: 1.8 g (92%).
