Versuchsvorschrift

To a solution of tert-butyl {3-[(5-cyano-2-[(1-methyl-1H-pyrazol-4-yl)amino]-7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)oxy]cyclobutyl}carbamate (cis:trans (1:1), 470 mg, 0.85 mmol) in DCM (20 mL) was added HCl (0.85 mL of 4 M in 1,4-dioxane, 3.4 mmol). After 20 hrs, the volatiles were removed and 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 to give the title compound (380 mg, 99% yield) as a 1:1 cis:trans isomeric mixture. 1H NMR (400 MHz, DMSO-d6) δ ppm 9.41 (d, J=12.59 Hz, 1H) 8.10 (s, 1H) 7.96 (br. s., 1H) 7.55 (s, 1H) 5.53 (br. s., 2H) 3.82 (s, 3H) 3.61-3.73 (m, 1H) 3.52-3.60 (m, 4H) 3.04 (br. s., 1H) 2.71-2.85 (m, 1H) 2.15-2.40 (m, 2H) 1.76-1.92 (m, 1H) 0.76-0.91 (m, 1H) −0.12 (br. s., 9H). m/z (APCI+) for C21H30N8O2Si 455.1 (M+H)+.
