Reaction Steps

Following the procedure as described in PREPARATION 2A and making non-critical variations using 2,1,3-benzoxadiazol-5-ol to replace 3-bromophenol, and 1-(diphenylmethyl)-1H-indole-2,3-dione to replace 1-((5-(trifluoromethyl)furan-2-yl)methyl)indoline-2,3-dione, 1-(diphenylmethyl)-3-hydroxy-3-(5-hydroxy-2,1,3-benzoxadiazol-4-yl)-1,3-dihydro-2H-indol-2-one was obtained (71%) as a colorless solid: MS (ES+) m/z 472.0 (M+23).
