実験手順

To a solution of 2.01 g (4.87 mM) of tert-butyl 4-(diethoxyphosphorylmethanesulfonylmethyl)piperidine-1-carboxylate in 30 ml of toluene was added 0.18 g (4.43 mM) of a 60% suspension of sodium hydride in liquid paraffin at room temperature, and the mixture was stirred at the prevailing temperature for 1 hour. This reaction mixture was added to a solution of the above crude 5-thia-1,8b-diazaacenaphthylene-4-carbaldehyde in N,N-dimethylformamide (10 ml)-toluene (30 ml) at room temperature and the mixture was stirred at the prevailing temperature for 0.5 hour. This reaction mixture was poured in water 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 purified by silica gel column chromatography (ethyl acetate˜ethyl acetate/methanol=9/1) to provide crude (E)-4-[2-[1-(tert-butoxycarbonyl)piperidin-4-ylmethane-sulfonyl]viny]-5-thia-1,8b-diazaacenaphthylene. This crude product was not purified but used as it was in the next reaction.
