Reaction Steps

A solution of (2S,4S)-4-(4-amino-5-((3,5-dimethoxyphenyl)ethynyl)-7H-pyrrolo[2,3-d]pyrimidin-7-yl)-1-(tert-butoxycarbonyl)pyrrolidine-2-carboxylic acid (25.4 mg) obtained in Example 68 (Step 1), TBTU (17.7 mg), N,N,N′-trimethylethane-1,2-diamine (13 μl), and DIPEA (26 μl) in acetonitrile (3 ml) was stirred at room temperature for 1 hour. Ethyl acetate and water were added to separate the organic layer. The organic layer was dried over anhydrous sodium sulfate, and the solvent was distilled off under reduced pressure. The resulting residue was purified by basic silica gel column chromatography (developing solvent: chloroform/methanol) to obtain the title compound as a light-yellow, amorphous substance (3 mg). Physical properties: m/z [M+H]+ 592.4
