Procedure

In a manner similar to the method described in example 1e, E/Z-6-chloro-3-(3-chloro-benzylidene)-2-oxo-2,3-dihydro-indole-1-carboxylic acid tert-butyl ester prepared in example 5b (1.1 g, 2.8 mmol) was reacted with (R/S)-1-[2-(1-tert-butoxycarbonyl-3-pyrrolidinyloxy)-5-iodo-phenyl]-3-trimethylsilyoxy-2-aza-1,3-butadiene (5.3 g, 10 mmol) in toluene (30 mL) at 140° C. for 4 h to give racemic(2′R, 3R, 4′S)-2′-[2-(1-tert-butoxycarbonyl-3-pyrrolidinyloxy)-5-iodo-phenyl]-6-chloro-4′-(3-chlorophenyl) spiro[3H-indole-3,3′-piperidine]-2,6′(1H)-dione as a yellow solid (Yield 0.5 g, 48%)
