Versuchsvorschrift

Reaction was carried out in the same manner as in Example 2-(a) except for using tert-butyl(tert-butoxycarbonyl{6-[(pyridin-3-ylsulfonyl)aminomethyl]pyridin-2-yl}amino)acetate (69.4 mg, 0.145 mmol) obtained in Reference Example 12-(d) in place of N-[4-(thiazol-2-yl)benzyl]pyridin-3-ylsulfonamide, and using (6-methoxybenzo[b]-thiophen-2-yl)methanol (see WO 2006/106711A, 33.9 mg, 0.175 mmol) in place of tert-butyl [tert-butoxycarbonyl(6-hydroxymethylpyridin-2-yl)amino]acetate. After completion of the reaction, the reaction solution was concentrated under reduced pressure, and water was added to the residue, followed by extraction with toluene. The separated organic layer was dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The resulting residue was subjected to silica gel column chromatography (eluent; hexane:ethyl acetate=3:1→1:1 (V/V)) and then to reversed phase column chromatography (column; Megabond Elut™ C18 (manufactured by Varian, Inc.), eluent; acetonitrile:water=1:1→1:0 (V/V)), and fractions containing the desired compound were concentrated under reduced pressure to afford the title compound (73.8 mg) as a white foam. (Yield: 78%)
