Procedure

Following the procedure as described in PREPARATION 2A and making non-critical variations using 2,3-dihydrobenzofuran-6-ol to replace 3-bromophenol, and 6-(diphenylmethyl)-2,3-dihydro-6H-[1,4]dioxino[2,3-f]indole-7,8-dione to replace 1-((5-(trifluoromethyl)furan-2-yl)methyl)indoline-2,3-dione, 6-(diphenylmethyl)-8-hydroxy-8-(6-hydroxy-2,3-dihydro-1-benzofuran-5-yl)-2,3,6,8-tetrahydro-7H-[1,4]dioxino[2,3-f]indol-7-one was obtained (94%) as a colorless solid: MS (ES−) m/z 506.1 (M−1).
