Procedure

Following the procedure as described in PREPARATION 4C, and making non-critical variations using 7-chloro-1-(diphenylmethyl)-3-hydroxy-3-(6-hydroxy-2,3-dihydro-1-benzofuran-5-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, 7-chloro-1-(diphenylmethyl)-3-(6-hydroxy-2,3-dihydro-1-benzofuran-5-yl)-1,3-dihydro-2H-indol-2-one was obtained (64%) as a colorless solid: 1H NMR (300 MHz, DMSO-d6) δ9.53 (s, 1H), 7.44-7.20 (m, 13H), 7.01-6.91 (m, 2H), 6.22 (s, 1H), 4.82 (s, 1H), 4.48 (t, J=8.5 Hz, 2H), 3.03 (t, J=8.5 Hz, 2H).
