Reaction Steps

A mixture of 4,6-dichloro-2-(2,4-dimethoxybenzyl)-7-fluoro-1H-pyrrolo[3,4-c]pyridin-3(2H)-one (200 mg, 0.539 mmol), (R)-2-amino-4-methylpentanamide (140 mg, 1.078 mmol), and N-isopropyl-N-methylpropan-2-amine (310 mg, 2.69 mmol) in acetonitrile (2 mL) was stirred at 85° C. for 3 d. The resulting crude material was reconstituted in MeOH/DCM/DMF (10.0 mL) and purified via preparative HPLC. The fractions were collected and stripped to dryness via rotary evaporation to yield the title compound (83 mg, 33%). [M+H] calc'd for C22H26ClFN4O4, 465; found, 465.
