Methanaminium, N-((dimethylamino)(3H-1,2,3-triazolo(4,5-b)pyridin-3-yloxy)methylene)-N-methyl-, hexafluorophosphate(1-) (1:1) → HCID 58394291, compound

Participants

Reaction Steps

To a solution of 5′-methyl-5-(1-pyrrolidinyl)-2,3′-bipyridine-4-carboxylic acid (2-2, 0.026 g, 0.085 mmol) and 1-(5,6-dimethoxy-2-pyridinyl)methanamine (3-6, 0.017 g, 0.102 mmol) in DMF (0.17 mL) was added HATU (0.032 g, 0.085 mmol) followed by DEA (0.074 mL, 0.426 mmol) and stirred at ambient temperature for 1 h. The system was partitioned between saturated aqueous sodium bicarbonate and EtOAc, washed with brine and dried over magnesium sulfate. Filtration and concentration followed by purification via normal phase chromatography (0→10% MeOH in EtOAc) afforded the title compound (2-3) as a salmon powder. 1H NMR (500 MHz, CDCl3) δ 8.93 (s, 1H), 8.40 (m, 1H), 8.32 (s, 1H), 8.06 (m, 1H), 7.08 (s, 1H), 7.06 (d, 1H, J=8.0 Hz), 6.90 (d, 1H, J=8.0 Hz), 4.63 (d, 2H, J=4.5 Hz), 4.00 (s, 3H), 3.89 (s, 3H), 3.36 (m, 4H), 2.40 (s, 3H), 1.93 (m, 4H). HRMS[M+H]C24H22N5O3 calc'd 434.2187. found 434.2211.
