1-Hydroxybenzotriazole → HCID 18349095, compound

Participants

Reaction Steps

To a stirred solution of 3-bromo-5-[2-(pyridin-4-ylamino)-ethoxy]-benzoic acid trifluoroacetate salt (0.034 g), TBTU (0.048 g) and HOBt (0.014 g) in DMF (0.3 ml) was added DIPEA (0.026 ml) followed by N-allylcyclopentyamine (0.022 ml) after 15 min. The reaction mixture was stirred at room temperature for 18 h and then concentrated under reduced pressure. The residue was subjected to preparative hplc and the title compound (0.022 g) was obtained as a colourless gum by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure.
