Versuchsvorschrift

Benzyl N-[(1S,3R)-3-cyanocyclohexyl]carbamate (0.26 g, 1.02 mmol) was dissolved in THF (15 mL) and treated with 0.13 g of 20% Pearlman's catalyst (50% wet by weight). The suspension was degassed with hydrogen for 2 min then placed under static hydrogen atmosphere. After 135 min, TLC showed no remaining starting material. The suspension was filtered through celite, washed with THF and degassed with nitrogen followed by the addition of iPr2NEt (0.21 mL, 1.23 mmol) and 5-chloro-3-(5-fluoro-4-(methylsulfinyl)pyrimidin-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine, 1a, (0.48 g, 1.02 mmol). The mixture was allowed to stir overnight at 45° C. then concentrated to dryness, absorbed on silica-gel and purified by silica gel chromatography using 0-60% EtOAc/hexanes gradient to afford 293 mg of a white solid.
