Reaction Steps

To a solution of 4-(1-acetyl-2,3-dihydro-1H-indol-5-yl)pyrimidin-2-amine (1.27 g) in ethanol (60 mL) and 1,4-dioxane (40 mL) was added sodium hydroxide (pellet) (2.8 g) and the mixture was refluxed for 6 hours. The resultant solution was cooled to ambient temperature and neutralized by addition of 1N hydrochloric acid. The mixture was evaporated in vacuo and the residue was extracted with chloroform. The organic layer was washed with brine, dried over magnesium sulfate and evaporated in vacuo to afford crude 4-(2,3-dihydro-1H-indol-5-yl)pyrimidin-2-amine (1.03 g) as a powder.
