Versuchsvorschrift

Tert-butyl 4-(2-cyano-1-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)ethyl)piperidine-1-carboxylate (59.4 mg, 0.118 mmol) was dissolved in DCM (592 μL, 0.118 mmol). To this was added 4N HCl in dioxane (296 μL, 1.18 mmol) and stirred at ambient temperature for 1 hour. Complete conversion was observed after 1 hour and the reaction mixture was concentrated to dryness to afford the HCl salt of 3-(4-(7-(1-methyl-1H-pyrazol-4-yl)imidazo[1,2-c]pyrimidin-5-yl)-1H-pyrazol-1-yl)-3-(piperidin-4-yl)propanenitrile (56.0 mg, 99.7% yield). MS (apci) m/z=402.3 (M+H).
