Procedure

A mixture of 8-chloro-1-(piperidin-4-yl)-1H-[1,2,3]triazolo[4,5-c][1,5]naphthyridine (200 mg, 0.69 mmol), isobutyric acid (67 mg, 0.76 mmol), HATU (315 mg, 0.83 mmol) and DIEA (133 mg, 1.04 mmol) in DMF (5 mL) was stirred at r.t. overnight. Then water (10 mL) was added; the precipitate was collected and dried in vacuo to afford 1-(4-(8-chloro-1H-[1,2,3]triazolo[4,5-c][1,5]naphthyridin-1-yl)piperidin-1-yl)-2-methylpropan-1-one as a solid (200 mg).
