4 -Cyclohexyl-2-cyclohexylcarbonyl

Treatment of 2-benzoyl-l,2,3,6,7,l lh-hexahydro-4//-pyrazino[2,l-a]-isoquinolin-4-one with NaNH2, then with ethylene oxide yielded the 3-(2-hydroxyethyl) derivative (76GEP2441261). 4-Thioxo and 2-(cyclohexyl-thiocarbonyl)-4-thioxo derivatives were prepared from 1,2,3,6,7,116-hexa-hydro-4//-pyrazino[2,l-a]isoquinolin-4-one and its 2-cyclohexylcarbonyl derivative by treatment with P4Si0.
