Following the procedure as described in PREPARATION 4C, and making non-critical variations using 1-(diphenylmethyl)-3-hydroxy-3-(2-hydroxy-4,5-dimethylphenyl)-1,3-dihydro-2H-indol-2-one to replace 4-chloro-1-(diphenylmethyl)-3-hydroxy-3-(6-hydroxy-2,3-dihydro-1-benzofuran-5-yl)-1,3-dihydro-2H-indol-2-one, 1-(diphenylmethyl)-3-(2-hydroxy-4,5-dimethylphenyl)-1,3-dihydro-2H-indol-2-one was obtained (93%): 1H NMR (300 MHz, CDCl3) δ 7.34-7.27 (m, 11H), 7.06-7.02 (m, 3H), 6.76 (s, 1H), 6.72 (s, 1H), 6.55-6.50 (m, 1H), 5.05 (s, 1H), 2.17 (s, 3H), 2.12 (s, 3H); MS (ES+) m/z 420.2 (M+1).
