24.89 g (142.56 mmol) of 2-fluoro-3-methoxybenzyl chloride is stirred in 200 ml of DMSO with 8.38 g (171.07 mmol) of sodium cyanide for three hours at 90° C. The reaction mixture is poured into water and extracted four times with methyl tert-butyl ether. The combined organic phases are washed with brine, dried, the desiccant is suctioned off, and the solvent is spun off. First, only a portion of the residue (21.43 g) is incorporated in crude form into the next stage.
