Procedure
The title compound was prepared by a similar process to that described for Intermediate 53 but using (4-methoxyphenyl)(phenylsulfonyl)methylformamide (Tetrahedron Lett., 1996, 37 (45), 8113) in place of {(3-iodophenyl)[(4-methylphenyl)sulfonyl]methyl}formamide (Intermediate 52). Tan solid (26.15 g, 97%)
