合成路线1
该中间体在本合成路线中的序号：(XXIV)Alternatively, condensation of 1,7-dichloro-4-methoxyisoquinoline (XXI) with 1-(tert-butoxycarbonyl)-4(R)-hydroxy-L-proline (XVI) in the presence of t-BuOK in DMSO gives 1-(tert-butoxycarbonyl)-4(R)-[(7-chloro-4-methoxyisoquinolin-1-yl)oxy]-L-proline (XXIV), which is then coupled with 1(R)-amino-2(S)-vinylcyclopropanecarboxamide (XI) by means of EDC, HOBt and DIEA , or HATU and DIEA in CH2Cl2 , to yield the corresponding dipeptide derivative (XXV). NBoc cleavage by means of HCl in i-PrOH (1) or refluxing MeOH provides amine hydrochloride (XXVI), which is finally condensed with N-(tert-butoxycarbonyl)-3-methyl-L-valine (XIX) using HATU and DIEA in .
