Reaction Steps

To a solution of 5-[(4-methylphenyl)sulfonyl]-4,5,6,7-tetrahydrofuro[3,2-c]pyridine-2-carboxylic acid (1.0 eq) obtained from step II in DMF was added Et3N (2.2 eq.), EDCI (1.2 eq) and HOBt ((1.2 eq) and reaction was stirred for 1 h Phenylene diamine was added to reaction mass and stirred for overnight. Reaction was quenched with water and the organic layer was separated, dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford crude product, which, on purification by column chromatography afforded the title compound.
