Versuchsvorschrift

To a solution of 4-[(3-aminocyclobutyl)oxy]-2-[(1-methyl-1H-pyrazol-4-yl)amino]-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidine-5-carbonitrile (cis:trans 1:1) (380 mg, 0.84 mmol) in DCM (10 mL) was added acryloyl chloride (68 μL, 0.84 mmol) and DIPEA (146 μL, 0.84 mmol). The reaction solution was stirred at rt for 10 min. The reaction mixture was partitioned between DCM (50 mL) and saturated aqueous NaHCO3 (20 mL). The organic layer was separated, dried over Na2SO4 and evaporated. The product was purified via flash chromatography eluting with a gradient of 0%-100% EtOAc in heptanes to give the title compound (317 mg, 75% yield) as a 1:1 cis:trans isomeric mixture. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.43 (s, 1H) 8.42-8.63 (m, 1H) 8.11 (s, 1H) 7.96 (br. s., 1H) 7.43-7.62 (m, 1H) 6.00-6.31 (m, 2H) 5.61 (ddd, J=9.69, 7.05, 2.64 Hz, 3H) 4.07-5.26 (m, 2H) 3.81 (d, J=5.79 Hz, 3H) 3.56 (t, J=7.93 Hz, 2H) 2.84-2.99 (m, 1H) 2.51-2.58 (m, 2H) 2.08-2.20 (m, 1H) 0.84 (t, J=8.06 Hz, 2H) −0.12 (br. s., 9H). m/z (APCI+) for C24H32N8O3Si 509.1 (M+H)+.
