A microwave vial was charged with a solution of N-((1S,3S,4R)-3-(3-(4-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-5-yl)propylamino)-4-ethylcyclopentyl)cyclopropanesulfonamide (0.200 g, 0.345 mmol) in 1-propanol (1.70 mL). DIEA (0.180 mL, 1.04 mmol) and potassium iodide (0.057 g, 0.345 mmol) were added and the reaction mixture was heated in a Biotage® microwave at about 150° C. for about 30 min. The reaction was resubmitted to microwave heating at about 180° C. for about 1 h. The reaction was resubmitted to microwave heating at about 180° C. for about 10 h. The reaction mixture was transferred to a round bottom flask and silica gel (about 1 g) was added. The solvent was removed under reduced pressure and the resulting silica gel mixture was purified by silica gel chromatography eluting with a gradient of 0-10% MeOH in DCM to give N-((1S,3R,4S)-3-ethyl-4-(7-tosyl-2,3,4,7-tetrahydro-1H-pyrrolo[2,3-h][1,6]naphthyridin-1-yl)cyclopentyl)cyclopropanesulfonamide (0.050 g, 27%) as a yellow foam: LC/MS (Table 1, Method b) Rt=2.52 min; MS m/z: 543 (M+H)+.
