Reaction Steps

To a cold solution of 2-methyl-1,2,3,4-tetrahydro-4-(p-trifluoromethylphenoxy)isoquinoline of Example 4 (23 g, 0.075 mole) in 150 ml dichloromethane, is added 25 g K2CO3, followed by a solution of phenyl chloroformate (15.6 g, 0.1 mole) in 100 ml dichloromethane. After stirring at ambient temperature for twenty hours, the mixture is filtered, and the solvent evaporated to an oil, which solidifies to a solid upon trituration with hexanes, 24 g (80%), m.p. 72° C. A sample of this material is recrystallized twice from hexanes, to yield 2-phenoxycarbonyl-1,2,3,4-tetrahydro-4-(p-trifluoromethylphenoxy)isoquinoline, m.p. 101°-3° C.
