A 100 mL RBF was charged with 5-chloroisoquinolin-4-carboxylic acid (1 equiv) in dry THF (20 mL), DIPEA (3 equiv), EDC.HCl (1.5 equiv), HOBT (1.5 equiv) under inert atmosphere and the mixture was stirred for 15 mins. To this, corresponding amine (1.2 equiv) was added dropwise and the reaction mixture was stirred overnight. After completion, it was diluted with EtOAc and water. The organic layer was then separated, dried and concentrated under reduced pressure to give the crude product that was purified by column chromatography using 100-200 silica gel (80% Ethyl acetate in Hexanes) to furnish the desired amide derivative in 70-84% yield.
