Reaction Steps
3.94 g of 4-bromomethyl-1-chloro-2-trifluoromethyl-benzene (14.4 mmol) and 1.06 g sodium cyanide (21.6 mmol) were suspended in 12 ml DMSO under argon and stirring and heated to 50° C. for 1 h. The reaction mixture was then poured on water/ice and extracted four times with DCM. The combined organic phases were washed with water, dried with magnesium sulfate, filtered and concentrated in vacuo, leading to 3.188 g of (4-chloro-3-trifluoromethyl-phenyl)-acetonitrile as a dark red oil, which was directly used in the next step.
