Reaction Steps

A mixture of 1-bromo-5-methyl-2-nitro-4-trifluoromethyl-benzene from step 2 (49.80 g, 175 mmol) and copper(I) cyanide (16.5 g, 184 mmol) in 1-methyl-2-pyrrolidone (NMP) (180 mL) was heated up to 150° C. and stirred for 30 min under nitrogen atmosphere. The mixture was cooled to 23° C. and poured into 1 N HCl, extracted with TBME, washed with brine and dried over Na2SO4. Removal of the solvent in vacuum left a brown oil, which was purified by silica gel column chromatography with heptane/ethyl acetate 4:1->2:1 to give the title compound as a light yellow solid (35.48 g, 88%). MS (EI) 230.1 [M].
