Reaction Steps

A mixture of tert-butyl (3S,5R)-3-[{[5-bromo-1-(4-methoxybutyl)-1H-pyrrol-2-yl]carbonyl}(2-methylpropyl)amino]-5-(morpholin-4-ylcarbonyl)piperidine-1-carboxylate (220 mg), pyridin-2-ylboronic acid (65 mg), sodium carbonate (370 mg), tetrakis(triphenylphosphine)palladium (40 mg), ethanol (2 ml), toluene (2 ml) and water (2 ml) was stirred at 80° C. for 12 hr. The solvent was evaporated under reduced pressure. The residue was dissolved in ethyl acetate-water, and the organic layer was washed with saturated brine, and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure. The residue was subjected to silica gel column chromatography, and a fraction eluted with ethyl acetate-hexane (1:1-1:0) was concentrated under reduced pressure to give the object product (240 mg).
