2-(Dimethylamino)ethanol → HCID 22405173, compound

Participants

Reaction Steps

To a solution of 1-carboxymethyl-5-{4-[2-(2-methylphenyl)benzoylamino]benzoyl}-1,3,4,5-tetrahydro-1,5-benzodiazepin-2(2H)-one (220 mg), 2-dimethylaminoethanol (37 mg) and 4-dimethylaminopyridine (10 mg) in dichloromethane (5 ml) were added dicyclohexylcarbodiimide (102 mg) at ambient temperature and the mixture was stirred at the same temperature for 30 hours. The resulting mixture was washed with saturated sodium bicarbonate aqueous solution. Drying over magnesium sulfate, filtering and the removal of solvents afforded a crude product. The crude product was purified by silica gel column (3% methanol in chloroform). The solvent was evaporated in vacuo and the residue was solidified with diethyl ether to give 1-[(2-dimethylaminoethoxy)carbonylmethyl]-5-{4-[2-(2-methylphenyl)benzoylamino]benzoyl}-1,3,4,5-tetrahydro-1,5-benzodiazepin-2(2H)-one (86 mg) as a white powder.
