Reaction Steps
Compound methyl 4-(6-acetyl-7-amino-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)benzoate was treated with 2 equivalents of LiOH and stirred at room temperature for 4 hrs. Neutralization with dil.HCl and extraction in to organic layer, gave the product, 4-(6-acetyl-7-amino-3-(6-phenylpyridin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)benzoic acid in quantitative yield. The compound dissolved in to water-acetonitrile and lyophilized to give a white powder. HPLC-MS tR=1.49 min (UV254 nm); mass calculated for formula C26H19N5O3 449.1, observed LCMS m/z 450.2 (M+H).
