Diisopropylethylamine → 2-{[{2-[3-(acetylamino)phenyl]-2-hydroxyethyl}(methyl)amino]methyl}-N-(4-chlorobenzyl)-3,4-dimethyl-7-oxo-4,7-dihydrothieno[3,2-b]pyridine-6-carboxamide

Reaction Steps

A mixture of N-(4-chlorobenzyl)-2-(chloromethyl)-3,4-dimethyl-7-oxo-4,7-dihydrothieno[3,2-b]pyridine-6-carboxamide (100 mg, 0.25 mmol), N-{3-[1-hydroxy-2-(methylamino)ethyl]phenyl}acetamide (Preparation 45) (79 mg, 0.38 mmol) and diisopropylethylamine (67 μL, 0.38 mmol) in dry DMF (5 mL) was heated to 60° C., becoming a solution. The reaction was stirred for 6 hours at that temperature. After cooling to room temperature, the solution was concentrated under high vacuum. The oil residue was purified with a silica gel chromatotron plate to give the title compound (62 mg) as a white solid.
