Reaction Conditions

Reaction Steps

In 30 ml of ethanol were dissolved 5.47 g of N-hexyl-N-(2-p-toluenesulfonyloxyethyl)-5-isoquinolinesulfonamide and 2.85 g of piperidine, and the solution was heated in a pressure vessel at 80° C. for 3 hours. To the mixture obtained was added 100 ml of chloroform, and the resultant mixture was washed with 100 ml of water and dried with anhydrous magnesium sulfate. The chloroform 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, solvent: 3% methanol solution in chloroform) to obtain 3.6 g of N-hexyl-N-(2-piperidinoethyl)-5-isoquinolinesulfonamide [Compound (45)]. Compound (45) was analyzed to give the following data.
