Reaction Steps
Following the procedure as described in EXAMPLE 3 and making non-critical variations using 6-bromo-1′-(diphenylmethyl)spiro[1-benzofuran-3,3′-indol]-2′(1′H)-one to replace 1′-(diphenylmethyl)-6-methoxy-5-methylspiro[1-benzofuran-3,3′-indol]-2′(1′H)-one, 6-bromospiro[1-benzofuran-3,3′-indol]-2′(1′H)-one was obtained (89%) as a colorless solid: MS (ES+) m/z 316.1 (M+1), 318.1 (M+1).
