Procedure

Following the procedure as described in PREPARATION 2A and making non-critical variations using 2,3-dihydrobenzo[b][1,4]dioxin-6-ol to replace 3-bromophenol, and 4,7-dimethoxy-1-[2-(2-methoxyethoxy)ethyl]-1H-indole-2,3-dione to replace 1-((5-(trifluoromethyl)furan-2-yl)methyl)indoline-2,3-dione, 3-hydroxy-3-(7-hydroxy-2,3-dihydro-1,4-benzodioxin-6-yl)-4,7-dimethoxy-1-[2-(2-methoxyethoxy)ethyl]-1,3-dihydro-2H-indol-2-one was obtained (53%): MS (ES+) m/z 443.9 (M−17).
