Reaction Steps

A mixture of N-isopropyl-3-(2-hydroxy-5-methylphenyl)-3-phenylpropylamine (59 g) and 3-(2-(benzyloxy)-5-methylphenyl)-3-phenylpropyl-4-methylbenzenesulfonate of Formula IVa (100 g) in acetonitrile (595 ml) was heated in an autoclave at 110-115° C. for 16-18 hours. The reaction mass was cooled to 60-65° C., and solvent was distilled completely under vacuum. Charged ethyl acetate (290 ml) and water (590 ml) to the residue. Separated the aqueous layer and extracted with 118 ml of ethyl acetate. Combined organic layers were washed with water (590 ml) and distilled completely to obtain 108 g of syrup. This syrup was loaded onto a silica gel column and eluted with 5% ethyl acetate in chloroform. Distilled the solvent completely to get 38 g of the title compound as syrup.
