Participants

Reaction Steps

5.8 g (0.05 mole) of diethylaminoethylamine are added dropwise to a stirred solution of 12.3 g (0.05 mole) of 4-methoxy-2-phenacylcyclohexanone in glacial acetic acid under nitrogen. After refluxing for 5 hours, ice and water are added and the aqueous solution is washed with ether. The ether solution is dried over sodium sulfate and concentrated to a brown oil. The oil is converted to the oxalate salt which is recrystallized from methanol to give 1-(2-diethylaminoethyl)-2-phenyl-5-methoxy-4,5,6,7-tetrahydroindole oxalate as tan crystals, dec. 172°-176° C.
