Reaction Steps

To a solution of 596 mg. (1.98 mmoles) of 3-[4-(1,1-dimethylheptyl)-2-hydroxyphenyl]-1,2,5,6-tetrahydropyridine in 2.25 ml. of toluene and 4.5 ml. of pyridine is added 180 μl (3.96 mmoles) of cyclopropanecarboxylic acid chloride in 2.25 ml. of toluene. The reaction mixture is stirred for one hour at 25° C. and for 0.5 hour at 80° C. Another 180 μl (3.96 mmoles) portion of cyclopropanecarboxylic acid chloride is added and the heating at 80° C. continued for 2 hours. The reaction mixture is cooled and added to 300 ml. of saturated sodium chloride. The quenched mixture is extracted with two 75 ml. portions of dichloromethane. The extract is washed once with 50 ml. of saturated sodium chloride, dried over magnesium sulfate and evaporated to yield an oil. A solution of this oil in 100 ml. of ether is added dropwise to a mixture of 3.0 g. (78.9 mmoles) of lithium aluminum hydride in 150 ml. of ether. The reaction mixture is refluxed for 17 hours, cooled in ice and decomposed by the addition of 3 ml. of water, 3 ml. of 15% sodium hydroxide and 9 ml. more of water. After stirring for 30 minutes at 25° C. the quenched reaction mixture is filtered and the filtrate evaporated to a solid. Recrystallization from dichloromethane and pentane gives 296 mg. (42%) of the title compound.
