実験手順

A mixture of (E/Z)-3-cyclopropyl-2-(trifluoromethyl)acrylic acid (30 mg, 0.17 mmol), (R)-3-(4-phenoxyphenyl)-1-(pyrrolidin-2-ylmethyl)-1H-pyrazolo[3,4-d]pyrimidin-4-amine (158 mg, 0.52 mmol), Triethylamine (18.2 mg, 0.18 mmol) and DMF (3 mL) were stirred at room temperature for 10 min. O-(7-Azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium PF6 (69 mg, 0.18 mmol) was added and the reaction mixture was stirred for 2 h. The solvent was evaporated and the oil was worked up with ethylacetate and water. The organic layer was washed with brine and dried over MgSO4. Purification with column chromatography (SiO2, MeOH|DCM with gradient form 1% to 2% in total 500 mL) gave (R)-1-(2-((4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl)methyl)pyrrolidin-1-yl)-3-cyclopropyl-2-fluoroprop-2-en-1-one. MS (pos. ion) m/z: 549 (M+1).
