実験手順

While 0.708 g (2.898 mM) of 3-(5-thia-1,8b-diazaacenaphthylen-4-yl)acrylic acid, 0.68 g (3.19 mM) of 1-(tert-butoxycarbonyl)piperidin-4-ylmethylamine, and 0.48 ml (3.48 mM) of triethylamine were stirred together in 10 ml of N,N-dimethylformamide, 0.53 ml (3.48 mM) of diethyl cyanophosphate was added dropwise at room temperature and the mixture was stirred at the prevailing temperature overnight. This reaction mixture was poured in aqueous solution of sodium hydrogen carbonate and extracted with 3 portions of ethyl acetate. The organic layers were pooled and dried over MgSO4 and the solvent was distilled off under reduced pressure. The residue was subjected to silica gel column chromatography (ethyl acetate to ethyl acetate-methanol=9/1) to provide crude N-[1-(tert-butoxycarbonyl)piperidin-4-ylmethyl]-3-(5-thia-1,8b-diazaacenaphthylen-4-yl)acrylamide.
