Procedure
1-(2,3,4,6-Tetra-O-acetyl-β-D-glucopyranosyl)-3-(5-bromo-2-thienylmethyl)-4-chlorobenzene obtained in Example 128-(4) and 4-cyanophenylboronic acid were treated in a manner similar to Example 168-(1) to give 1-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-4-chloro-3-(5-(4-cyanophenyl)-2-thienylmethyl)benzene as colorless powder. APCI-Mass m/Z 657/659 (M+NH4).
