Downstream synthetic route of 84468-15-5

84468-15-5, As the paragraph descriping shows that 84468-15-5 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.84468-15-5,Isoquinoline-5-sulfonyl chloride,as a common compound, the synthetic route is as follows.

REFERENTIAL EXAMPLE 1 In 200 ml of chloroform was dissolved 12.0 g of 1,2-diaminoethane, and to the solution was added dropwise 100 ml of a chloroform solution containing 4.55 g of 5-isoquinolinesulfonyl chloride under cooling with ice. After the dropwise addition of the chloroform solution, the mixed solution was stirred at a temperature of 20 C. to 25 C. for two hours, and then the reaction solution was extracted with a 10% aqueous hydrochloric acid solution. The pH of the aqueous layer was adjusted to 10 with a 10% aqueous sodium hydroxide solution, and the aqueous layer was extracted with chloroform. The chloroform layer extracted was washed with water and dried with anhydrous potassium carbonate. Then the chloroform was distilled from the chloroform layer, and the residue obtained was subjected to a column chromatography [silica gel: 200 g; developing solvent: 2% methanol/chloroform (volume ratio)] to give 3.3 g of N-(2-aminoethyl)-5-isoquinolinesulfonamide as an oily substance in a yield of 66%. The same procedures as described above were repeated using the compounds of Formula (V) as set forth in Table 1 under the reaction conditions as set forth in Table 1, and N-(omega-aminoalkyl)-5-isoquinolinesulfonamide as set forth in Table 1 were obtained.
