Under an argon atmosphere 3-[2-(1-Hydroxymethyl-cyclopropyl)-8-methoxy-[1,2,4]triazolo[1,5-a]pyridin-5-yl]-benzonitrile (compound 150) (0.03 g, 0.08 mmol) was dissolved in DMF (0.5 mL). NaH (0.02 g, 0.48 mmol) was added and the suspension was heated at 65° C. for 1 h after which 1-pyrrolidine carbonylchloride (0.088 mL, 0.8 mmol) was added. Stirring was performed at 65° C. for 1 h. The reaction mixture was cooled and aq. NaHCO3 and H2O was added. The aqueous phase was extracted with EtOAc (×2). The combined organic phases were dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by flash chromatography on silica using DCM:MeOH 99:1 as eluent to afford the title compound as a solid.
