실험 절차

To a solution of 17-ethyl-1-hydroxy-14-(tert-butyldimethylsiloxy)-12-[2'-(4"-(2"'-methanesulfonyloxyethyloxy)-3"-methoxycyclohexyl)-1'-methylvinyl]-23,25-dimethoxy-13,19,21,27-tetramethyl-11,28-dioxa-4-azatricyclo[22.3.1.04,9 ]octacos-18-ene-2,3,10,16-tetraone (26.5 mg) in dry tetrahydofuran (0.3 mL) was added 200 μL of a sodium morpholine solution (prepared by addition of 10 μL morpholine to a suspension of 2.3 mg sodium hydride in 0.5 mL of tetrahydrofuran) and the mixture heated to 70° C. After 6 hours, the mixture is cooled to room temperature and quenched by the addition of saturated ammonium chloride solution, extracted with ethyl acetate, and the organic portion dried over magnesium sulfate. Purification of the concentrate by flash chromatography on silica gel (ethyl acetate:hexane (2:1)+1% methanol, then 2% ammonium hydroxide, 5% methanol, in methylene chloride) gave the title compound (10 mg).
