실험 절차
To a solution of 300 mL of dry methanol was added 0.52 gm (0.023 mol) of sodium and the solution was stirred until all sodium was reacted. The solution was cooled to 0° C. and 19.5 gm (0.057 mol) of 2,2,2-trichloro-1-(4-iodo-1H-pyrrol-2-yl)-ethanone was added as a solid over a 15 min period. After 15 min at 0° C. the solution was warmed to room temperature and stirred for an additional 2 h. The solvents were removed at reduced pressure and the residue dissolved in diethyl ether. The ether layer was washed with H2O, saturated brine, dried (Na2SO4) and the solvents removed at reduced pressure. The solid was recystallized from hot hexanes-trace EtOAc to yield 13.7 gm (95% yield) of a light brown solid. This was used without further purification.
