Versuchsvorschrift

Intermediate 5-2 (0.39 g), HATU (0.57 g) and DIPEA (0.80 mL) were added to a DMF (6.0 mL) solution of 4′-(methoxymethyl)biphenyl-4-carboxylic acid (0.36 g) as obtained in Example 3-(3), and the mixture was stirred for 30 minutes at 80° C. Then, brine was added to the reaction mixture, the mixture was extracted with ethyl acetate, and the organic layer was dried over anhydrous magnesium sulfate. The desiccant was filtered out, and the filtrate was concentrated under reduced pressure. The resulting residue was purified by NH type silica gel chromatography (gradient elution with hexane/ethyl acetate=50/50→0/100) to obtain 4-(methoxymethyl)-4′-{[1-methoxy-3-(methylamino)-1,3-dioxopropan-2-yl](methyl)carbamoyl}biphenyl (yellow oil) (0.40 g, 69%).
