Procedure

To 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) and tert-butyl (1R,2S)-2-aminocyclohexylcarbamate (173 mg, 0.808 mmol) in ACN (5 mL) was added N,N-diisopropylethylamine (0.141 mL, 0.808 mmol). The reaction mixture was heated in a sealed vial at 100° C. for several hours after which additional amine (0.5 eq) was added. The mixture was heated overnight and the solvent was subsequently removed in vacuo. The residue was dispersed in DMSO and MeOH (1/1) and the resulting mixture was filtered. The filtrate was purified via preparative HPLC. The fractions were collected and dried in vacuo to give the title compound as a tan solid (60.7 mg, 21%). [M+H] calc'd for C27H34ClFN4O5, 550. found, 550
