HCID 20773481tert-Butyl 7-[({2-[(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)amino]pyridin-3-yl}carbonyl)amino]-4,4-dimethyl-3,4-dihydroisoquinoline-2(1H)-carboxylate

Procedure

A mixture of 7-[(2-fluoro-pyridine-3-carbonyl)-amino]-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (0.187 g), C-(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-yl)-methylamine HCl salt (0.098 g, step B), DIEA (1.0 mL) and IpOH (1.5 mL) was subjected to a Microwave condition (170° C., 1000 s). Solvent was removed and the residue was purified by chromatography through silica gel (70 g, 1-4% MeOH/CH2Cl2 with 1% NH4OH, stepwise gradient) to afford 7-({2-[(2,3-dihydro-1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-amino]-pyridine-3-carbonyl}-amino)-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester as cream color solid. MS: (ES+) 529 (M+H). Calc'd. for C30H36N6O3—528.65.
