A solution of potassium cyanide (0.68 g, 0.010 mol) in water (3.0 mL) was added under nitrogen to a cooled (with an ethylene glycol/water (4/1)/dry ice bath) solution of 1,3-benzothiazol-6-ylmethanol in DMF (30 mL). The reaction mixture was warmed to 0° C., and stirred for 30 min. Water was added and the reaction mixture was extracted with DCM. The organic layer was washed with brine, dried over Na2SO4, filtered, and concentrated under reduced pressure. The residue was flash chromatographed on a silica gel column with ethyl acetate in hexane from 10-30% to afford the desired product (1.07 g). Analytical LCMS: (M+H)+=175.2.
