Reaction Steps

To 50 ml of methanol were added 2.47 g of the thus obtained 1-(1-chloro-5-isoquinolinesulfonyl)-3-piperidone, 1.11 g of n-hexylamine hydrochloride and 0.50 g of sodium cyanoborohydride, followed by stirring at 20° C. for 15 hours. The methanol was removed under reduced pressure, and 50 ml of chloroform was added to the resultant product. Then, the mixture was washed twice with 50 ml each of water and then washed once with 50 ml of a 50% aqueous sodium hydrogencarbonate solution, and dried with anhydrous sodium sulfate. The solvent was removed under reduced pressure to obtain a residue. The residue thus obtained was subjected to purification by silica gel column chromatography (Wacogel C-200, 100 g; solvent: chloroform) to obtain 2.54 g of 1-(1-chloro-5-isoquinolinesulfonyl)-3-hexylaminopiperidine [Compound (98)]. Compound (98) was analyzed to give the following data.
