Participants

Reaction Steps

1-(2,2-dimethylpropyl)-3-methyl-5-[3-(piperazin-1-ylmethyl)phenyl]-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (46-1) (50 mg, 0.13 mmol, 1.0 eq.) was dissolved in NMP (0.50 mL). Cyclopropanecarboxylic acid (16.4 mg, 0.19 mmol, 1.5 eq.) was added followed by N,N-diisopropylethylamine (0.07 mL, 0.38 mmol, 3.0 eq.) and HATU (72.5 mg, 0.19 mmol, 1.5 eq). The reaction stirred at ambient temperature for 5 minutes. The reaction was diluted with methanol, passed through a syringe filter and purified by reverse phase chromatography (15-95% H2O/Acetonitrile with 0.1% TFA modifier over 15 minutes) to afford 2-methylpropyl 5-(3-{[4-(cyclopropylcarbonyl)piperazin-1-yl]methyl}phenyl)-1-(2,2-dimethylpropyl)-3-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (48-1) as a white solid. HRMS (M+H)+: observed=462.2862, calculated=462.2864.
