실험 절차

A solution of 3-methanesulfonyl-azetidine (10.95 mg, 0.08 mmol) (Pharmablock Co. Ltd, cat# PBJH0053), 2-(3-fluoro-2-methylquinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (126) (24 mg, 0.081 mmol) and DIEA (15.50 μL, 0.09 mmol) in 0.5 mL of NMP was heated in a microwave at 125° C. for 30 min. Purification of the crude reaction mixture on a silica gel column (1-6% MeOH in DCM) gave 2-(2-methyl-3-(3-(methylsulfonyl)azetidin-1-yl)quinoxalin-5-yl)-6,7-dihydro-1H-pyrrolo[3,2-c]pyridin-4(5H)-one (16 mg, 48% yield) as a yellow crystalline solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 11.83 (1H, br.), 7.93 (1H, m, 7.65 (1H, m), 7.44 (1H, m), 7.14 (1H, s), 6.99 (1H, br.), 4.72 (2H, m), 4.60 (2H, m), 4.48 (1H, m), 3.43 (2H, m), 3.15 (3H, s), 2.89 (2H, m), 2.63 (3H, s). m/z (ESI, +ve) 12.1 (M+H)+.
