2-Methylpiperidine → HCID 53687742, compound

Participants

Reaction Steps

To a stirred solution of 3-[2-(tert-butoxycarbonyl-pyridin-4-yl-amino)-ethoxy]-5-chloro-benzoic acid (0.060 g) in dichloromethane (4 ml) was added DMF (0.025 ml) followed by 2M oxalyl chloride solution in dichloromethane (0.091 ml). The resultant solution was stirred at room temperature for 1 h, and then 2-methylpiperidine (0.03 g) followed by DIPEA (0.080 ml) were added. After 3 h, the solution was concentrated under reduced pressure and the residue was subjected to preparative hplc. The title compound (0.080 g) was obtained as a colourless oil by concentration of the required fraction under reduced pressure and drying by repetitive addition of acetonitrile and concentration under reduced pressure.
