Reaction Steps

A mixture of 3-chloro-N-[(1S)-2-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-1-({4-[8-(1-hydroxyethyl)imidazo[1,2-a]pyridin-2-yl]phenyl}methyl)ethyl]-4-[(1-methylethyl)oxy]benzamide (2.10 g, 3.30 mmol) and hydrazine monohydrate (0.83 g, 16.5 mmol) in ethanol (30 mL) was heated at 57° C. overnight. The reaction was cooled, diluted with ethanol, filtered, and concentrated to give the title compound (1.67 g, 100%) as a pale yellow powder. MS (ES+) m/e 507 [M+H]+.
