Cyclopropylamine → Ethyl 4'-(3-cyclopropylaminopropoxy)-3'-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate

Participants

Reaction Steps

In a manner similar to that of Example 1c, by reaction of 1.7 ml (24.5 mmol) of cyclopropylamine with 670 mg (1.12 mmol) of ethyl 4′-(3-iodopropoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate (obtained in Example 1b) in 50 ml of ethanol. 350 mg of ethyl 4′-(3-cyclopropylaminopropoxy)-3′-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphth-2-yl)biphenyl-4-carboxylate are obtained in the form of a white solid (m.p.=141° C., yield=59%).
