Procedure

A solution of 0.1 g of potassium hydroxide in 1ml of DMSO was stirred at room temperature for 10 minutes and then 0.1 g of N-[4-(3-dimethylaminopyrrolidin-1-yl)-phenyl]-6-hydroxynicotinamide was added. The reaction solution was stirred for 10 minutes and then 0.084 g of 1-bromobutane was added. The mixture was stirred at room temperature overnight. After addition of water and ethyl acetate, the aqueous phase was extracted three times with ethyl acetate. The combined organic phases were dried over sodium sulfate, concentrated in vacuo and purified by preparative HPLC. This resulted in the product with the molecular weight of 382.24 (C22H30N4O2); MS (ESI): 383 (M+H+) as hydrotrifluoroacetate.
