Versuchsvorschrift

To a suspension of 4-(5-(4-fluorobenzyl)-1-(azetidin-3-yl)-1H-pyrazol-3-yl)pyridine (85 mg, 0.28 mmol) in DMF (3 mL) was added HOBt (45 mg, 0.33 mmol), EDCI (64 mg, 0.33 mmol), NMM (76 μL, 0.69 mmol) followed by imidazole-2-carboxylic acid (34 mg, 0.30 mmol) and the mixture stirred for 16 hours at room temperature. The volatiles were removed in vacuo and the residue purified directly by Biotage flash chromatography, eluting with 2-6% MeOH/DCM to yield a clear gum. Ether was added (5 mL) and the mix sonicated to give a white precipitate that was filtered off, washed with ether and dried in-vacuo to yield the title compound as a white solid, 78 mg, 70%. 1H NMR (400 MHz, DMSO-D6) δ ppm 13.04-13.12 (m, 1 H), 8.54 (d, 2 H), 7.74 (d, 2 H), 7.25-7.32 (m, 2 H), 7.18 (t, 2 H), 7.03-7.12 (m, 1 H), 6.66 (s, 1 H), 5.33-5.46 (m, 1 H), 4.77-4.92 (m, 2 H), 4.26-4.36 (m, 2 H), 4.12 (s, 2 H); m/z (APCI+) for C22H19N6FO 403.1 (M+H)+.
