実験手順

To a 10 ml seal tube, 4-(7-pivaloyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-ylamino)benzaldehyde (0.1 g, 0.00022 mol) and 2-(methylsulfonyl)acetonitrile (0.105 g, 0.00088 mol) were taken in ethanol (5 ml). Piperidine acetate (3.3 M solution in water) (1.0 ml) was added dropwise at RT. After completion of the addition, reaction mixture was refluxed for 24 hr. After completion of the reaction, ethanol was distilled out to obtain crude product. The crude product was purified by column chromatography using 30% ethyl acetate in hexanes to yield 0.078 g of 2-(methylsulfonyl)-3-(4-(7-pivaloyl-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazin-2-ylamino)phenyl)acrylonitrile which was converted to the title compound as described above.
