In a microwave vial 2,6-dichloro-quinoline-5-carboxylic acid (4,4-difluoro-cyclohexylmethyl)-amide (100 mg, 0.27 mmol), 3,3-difluoro-azetidine hydrochloride (347.07 mg, 2.68 mmol) and DIPEA (519.43 mg, 4.02 mmol) in ACN (1.5 mL) was heated at 120° C. for 2 hours under microwave irradiation. After cooling to room temperature, the mixture was concentrated and purified through reverse phase HPLC to provide the desired product (68 mg, 59%) as a solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 8.75 (1H), 7.88 (1H), 6.69 (1H), 4.54 (4H), 3.24 (t, J=6.24 Hz, 2H), 2.04 (m, 2H), 1.85 (m, 2H), 1.74-1.76 (m, 3H), 1.27-1.30 (m, 2H). m/z: 430 [M+H]
