Procedure

See FIG. 20(a). 1-((6-methoxy-5-methylpyrimidin-4-yl)methyl)-6-methyl-1H-pyrrolo[3,2-b]pyridine-3-carboxylic acid (75 mg, 0.24 mmol) was taken in dichloromethane (10 mL) to get a suspension. Added triethyl amine (0.0669 mL, 0.48 mmol) followed by the addition of 1-Propanephosphonic acid cyclic anhydride (0.286 mL, 0.48 mmol). The reaction mass was stirred at RT for 5 minutes. Ethanol amine (0.029 mL, 0.48 mmol) was added and stirred at RT for overnight. After the completion of the reaction, diluted the reaction mass with DCM, washed with water and brine solution. The DCM layer was dried over sodium sulphate, evaporated to get the crude compound which was purified by column chromatography. Yield-52.7%.
