Reaction Steps

Following the procedure as described in EXAMPLE 1.28, and making non-critical variations using 1′-(diphenylmethyl)-5-pyridin-3-ylspiro[1-benzofuran-3,3′-indol]-2′(1′H)-one to replace 1′-(diphenylmethyl)-5′-methylspiro[furo[2,3-f][1,3]benzodioxole-7,3′-indol]-2′(1′H)-one, the title compound was obtained that was used in the next step.
