Reaction Steps

A solution of 1-bromomethyl-2-trifluoromethyl-benzene (3.5 g, 14.641 mmol) in DMSO (18 mL) and sodium cyanide (1.076 g, 21.962 mmol) were taken in a flask and the flask was heated to 90° C. for 3 hours. The reaction was monitored by TLC (2% ethylacetate in hexane). The reaction mixture was partitioned between water and ethylacetate. The organic layer was washed with brine solution, dried over Na2SO4 and concentrated to afford 2.4 g of the crude product which was used in the next step without further purification.
