Procedure

3-(8-cyclopentyl-2-(ethylamino)-4-methyl-7-oxo-7,8-dihydropyrido[2,3-d]pyrimidin-6-yl)propanoic acid (94 mg, 0.27 mmole), dimethylamine (1.09 mmole, 0.55 ml of 2.0 M solution in THF), triethylamine (27.6 mg, 0.27 mmole), O-(7-Azabenzotriazole-1-yl)-N,N,N′N′-tetramethyluronium hexafluorophosphate (HATU, 104 mg, 0.27 mmole) and DMF (3.0 ml) were added to a reaction vial equipped with a stir bar. The reaction mixture was heated at 50° C. for 26 h. The reaction was quenched with water (2 ml), and the volatiles were removed under reduced pressure to a residue. Ethyl acetate (70 ml) and water (30 ml) were added and shaken well. The organic layer was separated, washed with water (2×30 ml), brine (30 ml), and dried over sodium sulfate. The solvent was removed under reduced pressure to a residue, which was purified using silica (100% petroleum ether to 100% ethyl acetate). The fractions were combined, and the volatiles were removed to a colorless oil as the title compound (55 mg, 54% yield).
