실험 절차

To a solution of 3-((S)-2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-oxopropanenitrile (236 mg, 0.5 mmol, 1 equiv) and tert-butyl ethyl(2-methyl-1-oxopropan-2-yl)carbamate (2.15 g, 10 mmol, 20 equiv) in dioxane (30 mL) was added 0.5 mL piperidine, 1 drop AcOH and 2 g of 4 A molecular sieves. The resulting mixture was stirred for 2 h at 110° C. The solids was filtered out, the filtrate was diluted with 200 mL of ethyl acetate, washed with brine, dried over Na2SO4, concentrated and purified by silica gel column (ethyl acetate/MeOH 10/1) to give 60 mg (19%) of tert-butyl 5-((S)-2-((4-amino-3-(2-fluoro-4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-4-cyano-2-methyl-5-oxopent-3-en-2-yl(ethyl)carbamate as a white solid.
