実験手順

In a manner similar to that of Example 1c, by reaction of 700 mg (1.3 mmol) of ethyl 4′-(4-chlorobutoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate with 800 μl (11.5 mmol) of cyclopropylamine in 100 ml of ethanol. 180 mg of ethyl 4′-(2-cyclopropylaminobutoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are obtained in the form of a yellow oil (yield=26%).
