実験手順

To a solution of 2-(N-(2-benzyloxy-5-bromobenzyl)-N-ethylamino]pyridine-5-carboxylic acid (0.89 g) in dichloromethane (50 ml) was added propanesulphonamide (0.3 g), dimethylaminopyrimidine (0.493 g) and 1-(3-dimethylaminopropyl)ethylcarbodiimide hydrochloride (0.58 g). The mixture was stirred at ambient temperature for 18 hours, and poured into 2N HCl. The organic layer was separated and washed with water and brine, then dried (MgSO4), filtered and evaporated. The resulting oil was purified by chromatography on silica gel (eluting with 5% ethylacetate/dichloromethane to give N-(2-[N-(2-benzyloxy-5-bromobenzyl)-N-ethylamino]pyridine-5-carbonyl)propanesulphonamide (271 mg) as a white foam.
