3-amino-cyclohexanol (Betapharma, 67.33 mg; 0.58 mmol; 2.0 eq.) was added to a mixture of N-(5-chloro[1,2,4]triazolo[1,5-a]pyridin-2-yl)nicotinamide ((B4), 80 mg; 0.29 mmol; 1.0 eq.), DIEA (76 mg; 0.58 mmol; 2.0 eq.) and activated Charcoal (8 mg) in tBuOH (0.8 mL). The reaction mixture was heated at 200° C. for 2×30 min under microwave irradiation. After this time, it was filtered on a celite pad and the cake was washed with ACN. The filtrate was directly purified by RP-HPLC (Starting with 15% ACN in water for 5 min, then up to 30% in 10 min.). The title compound was isolated after lyophilisation as a white powder (51 mg, 49%). HPLC, Rt: 2.14 min. (purity 98.0%). LC/MS, M+(ESI): 353.0, M−(ESI): 351.0.
