With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.6624-49-3,Isoquinoline-3-carboxylic acid,as a common compound, the synthetic route is as follows.

General procedure: At 0 ¡ãC and with stirring to the solution of 865 mg (5.0 mmol) of isoquinoline-3-carboxylic acid in 10 ml of anhydrous THF 675 mg (5.0 mmol) of HOBt was added to form reaction mixture A. The solution of 5.5 mmol of l-amino acid benzylester in 5 ml of anhydrous THF was adjusted pH 9 with triethylamine and stirred for 30 min to form mixture B. At 0 ¡ãC the mixtures A and B were mixed and then 1339 mg (6.5 mmol) of DCC was added. The reaction mixture was stirred at 0 ¡ãC for 2 h, at room temperature for12 h and TLC (ethyl acetate/petroleum ether, 1:2) indicated the complete disappearance of isoquinoline-3-carboxylic acid. The formed precipitates of DCU were removed by filtration and the filtrate was evaporated under vacumm. The residue was dissolved in 50 ml of ethyl acetate and the formed solution was washed successively with saturated aqueous solution of NaHCO3 (30 ml .x. 3), 5percent aqueous solution of KHSO4 (30 ml .x. 3) and saturated aqueous solution of NaCl (30 ml .x. 3) and dried over anhydrous Na2SO4. After filtration the filtrate was evaporated under vacumm and the residure was purified on silica gel chromatography (CHCl3:MeOH, 20:1) to give the title compounds., 6624-49-3
