2-Pyridinemethanamine → HCID 90386115, compound

Participants

Reaction Steps

To a stirred solution of 2,4,5-trichloropyrrolo[2,1-f][1,2,4]triazine (0.530 g, 2.38 mmol) in CH2Cl2 (20 mL) was added DIPEA (0.832 mL, 4.76 mmol) and pyridin-2-ylmethanamine (0.283 g, 2.62 mmol) and the contents were stirred for 10 min at room temperature. The reaction mixture was washed with water and the organic layer was separated, dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure to give a brown solid. The residue was purified by column chromatography using CombiFlash (REDISEP®, silica gel, 24 g, 20% EtOAc/hexanes) to give 2,5-dichloro-N-(pyridin-2-ylmethyl)pyrrolo[2,1-f][1,2,4]triazin-4-amine (0.400 g, 57.0%) as an off-white solid. LCMS Condition B-12: retention time 2.20, [M+1]=294.2. 1H NMR (400 MHz, DMSO-d6) δ ppm 4.87 (d, J=5.7 Hz, 2H), 6.81 (d, J=2.8 Hz, 1H), 7.32 (t, J=1.6 Hz, 1H), 7.42 (d, J=8.0 Hz, 1H), 7.81 (d, J=2.8 Hz, 1H), 7.83 (t, J=1.6 Hz, 1H), 8.48 (t, J=5.2 Hz, 1H), 8.57 (d, J=1.2 Hz, 1H).
