Reaction Steps

5-{[(2-Methylpropyl)amino]methyl}thiophene-2-carboxylic acid tert-butyl ester (0.55 g, 2.0 mmol) obtained in Example 24, step 1 and N-(1H-imidazol-1-ylcarbonyl)-allylamine (0.49 g, 3.2 mmol) obtained in step 1 were dissolved in acetonitrile (20 ml), N,N-diisopropylethylamine (0.56 mL, 3.2 mmol) was added, and the mixture was stirred at 60° C. overnight. The reaction mixture was concentrated under reduced pressure and the obtained residue was purified by column chromatography (hexane/ethyl acetate) to give the title compound (0.72 g, 2.0 mmol).
