実験手順

Following the procedure as described in PREPARATION 4C, and making non-critical variations using 1-(diphenylmethyl)-3-hydroxy-3-(5-hydroxy-2,3-dihydro-1,4-benzodioxin-6-yl)-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, (diphenylmethyl)-3-(5-hydroxy-2,3-dihydro-1,4-benzodioxin-6-yl)-1,3-dihydro-2H-indol-2-one was obtained (82%) as a colorless solid: 1H NMR (300 MHz, DMSO-d6) δ 9.11 (s, 1H), 7.39-7.24 (m, 9H), 6.95-6.79 (m, 3H), 6.58 (d, J=8.0 Hz, 1H), 6.35-6.30 (m, 2H), 4.21 (s, 4H).
