Procedure:
By use of general procedure B, 2-nitrobenzyl 2,3-bis(3,4,5-tris(benzyloxy)benzoyl)-β-D-glucopyranoside (2.10 g, 1.81 mmol) was coupled with 3-tert-butyldimethylsiloxy-4,5-diphenylmethylenedioxybenzoic acid (1.62 g, 3.62 mmol) to afford 2.99 g (80%) of 2-nitrobenzyl 4,6-bis(3-tert-butyldimethylsiloxy-4,5-diphenylmethylenedioxybenzoyl)-2,3-bis(3,4,5-tris(benzyloxy)benzoyl)-β-D-glucopyranoside as a white solid foam following flash column chromatography using 10%, and then 20%, EtOAc in hexanes as eluent.
