5-(2-Chloro-pyrimidin-4-yl)-2-pyrrolidin-1-yl-nicotinonitrile (9) (31 mg, 0.108 mmol) and 2-(4-amino-pyrazol-1-yl)-ethanol (32 mg, 0.252 mmol) were dissolved in 1,4-dioxane (1 mL). 4N HCl in 1,4-dioxane (30 μL, 0.120 mmol) was added and the mixture was heated at 140° C. in the microwave (250 W, stirring) for 90 minutes. The solvent was evaporated in vacuo and the residue dissolved in DMSO (1 mL). The crude product was purified twice by reversed phase preparative LC-MS. Fractions containing desired product were combined and the solvents evaporated in vacuo. The title compound was obtained as a yellow solid (3.7 mg, 9%); LCMS, Rt=7.43 min (Method C), m/z 377 (MH+).
