Reaction Steps

To a solution of (−)-8-(4-(2-butoxyethoxy)phenyl)-N-(4-(((1-propylimidazol-5-yl)methyl)sulfinyl)phenyl)-1,2,3,4-tetrahydro-1-benzazocine-5-carboxamide (120 mg) in 1,2-dichloroethane (10 ml), cyclopropanecarboxaldehyde (65.6 mg) and sodium triacetoxyborohydride (119 mg) were added. The mixture was stirred at room temperature for overnight. The reaction mixture was poured into water and extracted with ethyl acetate. The organic layer was washed with saturated NaHCO3, brine, and dried over MgSO4. The volatile materials were removed in vacuo and the residue was purified by column chromatography (basic silicagel, ethyl acetate) to give (−)-8-(4-(2-butoxyethoxy)phenyl)-1-(cyclopropylmethyl)-N-(4-(((1-propylimidazol-5-yl)methyl)sulfinyl)phenyl)-1,2,3,4-tetrahydro-1-benzazocine-5-carboxamide (55 mg) (compound 57) as a yellow amorphous.
