実験手順
Following the procedure as described in EXAMPLE 1.22, and making non-critical variations using ethyl [4-chloro-3-(6-hydroxy-2,3-dihydro-1-benzofuran-5-yl)-3-(hydroxymethyl)-2-oxo-2,3-dihydro-1H-indol-1-yl]acetate to replace 4,7-dichloro-3-(6-hydroxy-1,3-benzodioxol-5-yl)-3-(hydroxymethyl)-1-pentyl-1,3-dihydro-2H-indol-2-one, the title compound was obtained in 63% yield as a colorless solid: MS (ES+) m/z 400.8 (M+1).
