실험 절차

A solution of ethyl 2-(hydroxymethyl)-3,4-dimethyl-7-oxo-4,7-dihydrothieno[3,2-b]pyridine-6-carboxylate (627 mg, 2.23 mmol), 4-chlorobenzylamine (2.0 mL, 16.4 mmol), 0.5 M sodium methoxide in methanol (25 mL, 8.92 mmol) and methanol (10 mL) was stirred under nitrogen in a tightly capped 250 mL round bottom flask at 50° C. for 24 hours. The initial solution slowly dropped a thick white precipitate during the reaction. After cooling to room temperature, the mixture was filtered, and the collected solid was washed with methanol and dried in vacuo, leaving a white solid. The crude solid was suspended in boiling methanol (200 mL), cooled to room temperature, and filtered, to give the title compound as a white powder (585 mg).
