Procedure

A mixture of 2,3,4,5-tetrahydro-1-(p-trifluoromethylphenoxy)-3-benzazepine of Example 1 (16 g, 0.052 mole), chloroacetonitrile (8 g, 0.10 mole) and sodium bicarbonate (17 g, 0.20 mole) in DMF (125 ml) was warmed at 70° C. for 2.5 hours. The mixture was concentrated to an oil which was stirred with water and extracted with ethyl acetate. The organic extracts were washed twice with water and dried (saturated NaCl, anhydrous MgSO4). After filtering, the solvent was evaporated to an oil (18 g) which solidified upon triturating with petroleum ether to a solid (16.5 g, 92%, m.p. 125°-129° C. A sample was recrystallized from the hexanes to yield 3-cyanomethyl-2,3,4,5-tetrahydro-1-(p-trifluoromethylphenoxy)-3-benzazepine, m.p. 134°-135° C.
