Diisopropylethylamine → 4,4-dimethyl-7-({2-[(1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-amino]-pyridine-3-carbonyl}-amino)-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester

Participants

Reaction Steps

A mixture of 7-[(2-fluoro-pyridine-3-carbonyl)-amino]-4,4-dimethyl-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester (0.24 g), 1-(4-aminomethyl-pyrrolo[2,3-b]pyridin-1-yl)-ethanone (0.14 g), DIEA (0.8 mL) and IpOH (0.8 mL) was subjected to a MicroWave condition (170° C., 1000 s) twice. Evaporation of solvent yielded the crude compound, which was purified by chromatography through silica gel (15 g, 5% MeOH/CH2Cl2) to afford 4,4-dimethyl-7-({2-[(1H-pyrrolo[2,3-b]pyridin-4-ylmethyl)-amino]-pyridine-3-carbonyl}-amino)-3,4-dihydro-1H-isoquinoline-2-carboxylic acid tert-butyl ester.
