Reaction Steps
Hydrochloric acid (0.22 ml) was added to a stirred mixture of (2R)-1-[3,5-bis(trifluoromethyl)benzoyl]-4-[N-(2-hydroxybenzylidene)-2-aminoethyl]-2-(1H-indol-3-yl-methyl)piperazine (0.80 g), ethyl acetate (12 ml) and methanol (6 ml) at room temperature. The mixture was stirred at 50° C. for 4.5 hours and then concentrated in vacuo to give an oil. The oil was treated with 4N hydrogen chloride in dioxane solution (0.33 ml) to afford (2R)-4-(2-aminoethyl)-1-[3,5-bis(trifluoromethyl)benzoyl]-2-(1H-indol-3-yl-methyl)piperazine dihydrochloride (0.57 g).
