Reaction Steps

The mixture of 4-(3,4-Dichlorophenyl)-3,4-dihydro-N-methyl-1 (2H)-naphthalenimine (10 gm), 5% Pd/CaCO3 (grade-21, 0.6 gm), water (2 ml) and methanol (150 ml) is taken in a hydrogenation flask and then subjected to hydrogenation under a hydrogen pressure of 0.5 Kg at 20-35° C. for 3 hours 30 minutes. The catalyst is removed by filtration and the solvent is evaporated completely under vacuum to obtain cis-(+)-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-N-methyl-naphthalenamine. (cis-(+):trans-(+):99.8:0.2).
