Following the procedure as described in EXAMPLE 2 and making non-critical variations using 4-bromo-1-(diphenylmethyl)-3-(7-hydroxy-2,3-dihydro-1,4-benzodioxin-6-yl)-1,3-dihydro-2H-indol-2-one to replace 1-(diphenylmethyl)-3-(2-hydroxy-4-methoxy-5-methylphenyl)-1,3-dihydro-2H-indol-2-one, 4′-bromo-1′-(diphenylmethyl)-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (66%) as a colorless solid: 1H NMR (300 MHz, DMSO-d6) δ7.47-7.16 (m, 12H), 6.85 (s, 1H), 6.82-6.76 (m, 1H), 6.57 (s, 1H), 5.92 (s, 1H), 5.66 (ABq, 2H), 4.22-4.14 (m, 4H).
