HCID 593522481'-(diphenylmethyl)-7'-fluoro-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3'-indol]-2'(1'H)-one

Procedure

Following the procedure as described in EXAMPLE 2 and making non-critical variations using 1-(diphenylmethyl)-7-fluoro-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, 1′-(diphenylmethyl)-7′-fluoro-2,3-dihydrospiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (55%) as a colorless solid: MS (ES+) m/z 479.9 (M+1).
