Procedure

3-[8-(2,6-difluorophenyl)-2-(methylsulfonyl)-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-4-yl]-4-methyl-N-propylbenzamide (0.07 g, 0.13 mmol), N,N-dimethylethylenediamine (0.0173 g, 0.15 mmol), and TEA (0.026 g, 0.26 mmol) were combined in CH2Cl2 (5 mL) and stirred under argon at room temperature for 1 h. The solvents were pumped off in vacuo. The residue was flash chromatographed on silica gel (10 g) eluted with CH2Cl2 to 6:1:0.1, CH2Cl2:ethanol:NH4OH to give the title compound as a white amorphous solid. mp 139-142° C. LC-MS m/z 521 (M+H)+, 1.61 min (ret time).

Workup

  1. customchromatographed on silica gel (10 g)
  2. washeluted with CH2Cl2 to 6:1:0.1, CH2Cl2
