1-Hydroxybenzotriazole → HCID 57425298, compound

Participants

Reaction Steps

To a solution of 6-bromo-pyridine-2-carboxylic acid (100.00 mg, 0.50 mmol) in DCM (5.0 mL) was added 1-isopropylpiperazine (95.20 mg, 0.74 mmol) followed by 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC; 189.78 mg, 0.99 mmol), 1-hydroxybenzotriazole (HOBt; 133.78 mg, 0.99 mmol), and iPr2NEt (0.86 mL, 4.95 mmol). After 18 h at rt, the mixture was diluted with water and extracted with DCM. Purification by FCC provided the desired product (83.0 mg, 54%). MS (ESI): mass calcd. for C13H18BrN3O, 311.06; m/z found, 312.2 [M+H]+. 1H NMR (CDCl3): 7.69-7.59 (m, 2H), 7.56-7.52 (m, 1H), 3.84-3.76 (m, 2H), 2.79-2.68 (m, 1H), 2.62 (t, J=5.1 Hz, 2H), 2.53 (t, J=5.1 Hz, 2H), 1.06 (d, J=6.5 Hz, 6H). Assay 1 (Human H3): Ki=1400 nM.
