Procedure

See FIG. 18(a). 1-((6-methoxy-5-methylpyrimidin-4-yl)methyl)-1H-pyrrolo[3,2-b]pyridine-3-carboxylic acid (1 g, 3.35 mmol) was taken in DCM (20 mL) to get a suspension. Triethyl amine (1.394 mL, 10.06 mmol) was added followed by the addition of 1-Propanephosphonic acid cyclic anhydride (3.991 mL, 6.70 mmol). The reaction mass was stirred at RT for 5 minutes. Ethanol amine (6.02 mL, 10.06 mmol) was added and stirred at RT for 2 h. After completion of the reaction, diluted with DCM and then washed with water and brine solution. The organic layer was separated, dried, evaporated and the crude compound was purified by silica gel chromatography. Yield-45%. ES+MS m/z: 342 (M+1). 1H NMR (300 MHz, DMSO-d6) δ ppm 2.24 (s. 3 H ) 3.37-3.64 (m, 4 H ) 3.94 (s, 3 H ) 4.80 (t, J=4.99 Hz, 1 H ) 5.67 (s, 2 H ) 7.24 (dd, J=8.29, 4.52 Hz, 1 H ) 7.92 (d, J=8.10 Hz, 1 H ) 8.23 (s, 1 H ) 8.41 (s, 1 H ) 8.47 (d, J=4.52 Hz, 1 H ) 8.85 (t, J=5.37 Hz, 1 H ).
