Reaction Conditions

Reaction Steps

To a mixture of 1-(diphenylmethyl)hexahydro-1H-1,4-diazepine (2.0 g), N-(3-bromopropyl)phthalimide (2.01 g) and anhydrous potassium carbonate (3.1 g) was added acetone (10 ml) and then stirred for 6 hours at 50° C. The reaction mixture was filtered and the filtrate was concentrated in vacuo and then the resultant oily residue was subjected to a column chromatography on silica gel using a mixture of ethyl acetate and chloroform (2:3) for elution to give N-[3-{4-(diphenylmethyl)hexahydro-1H-1,4-diazepin-1-yl}propyl]phthalimide (2.2 g) as an oil.
