実験手順

To a suspension of 6-[({[1,6-diethyl-4-(tetrahydro-2H-pyran-4-ylamino)-1H-pyrazolo[3,4-b]pyridin-5-yl]methyl}amino)carbonyl]-2-pyridinecarboxylic acid (30 g, 66.3 mmol) in a 1 L round-bottom flask in dichloromethane (DCM) (300 mL) was added triethylamine (46.2 mL, 331 mmol) giving a solution to which was added TBTU (31.9 g, 99 mmol). The mixture became cloudy and was then stirred at room temperature under nitrogen for 5 min when 1-[3-bromo-4-(methyloxy)phenyl]methanamine hydrochloride (18.42 g, 72.9 mmol) was added. After 1.5 h the reaction was worked up. The mixture was partitioned between dichloromethane and water and the aqueous layer extracted well with dichloromethane. The combined organics were washed with saturated sodium bicarbonate, brine, dried (MgSO4), filtered and evaporated to give 52.41 g (121%) of a golden foam. The crude product was purified on a 750 g Companion XL silica cartridge, eluting with 20-100% of {1% MeOH in EtOAc) in dichloromethane over 12 column volumes. The fractions were checked by HPLC and product fractions were combined and solvent evaporated to give 30.15 g (˜65%) of a cream foam that lab HPLC showed to be 97.2% pure (ret time 2.11 min) LC-MS m/z 650, 652 (M+H)+, 1.03 min (ret time).
