Procedure

Following the procedure as described in EXAMPLE 3 and making non-critical variations using 1′-(diphenylmethyl)-9-fluoro-2,3-dihydro-spiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one to replace 1′-(diphenylmethyl)-6-methoxy-5-methylspiro[1-benzofuran-3,3′-indol]-2′(1′H)-one, 9-fluoro-2,3-dihydro-spiro[furo[2,3-g][1,4]benzodioxine-8,3′-indol]-2′(1′H)-one was obtained (72%) as a colorless solid: MS (ES+) m/z 313.8 (M+1).
