Procedure

To a stirred solution of 3-((1-(2-fluoro-4-iodophenyl)-3-(4-methoxybenzyl)-6,8-dimethyl-2,4,7-trioxo-1,2,3,4,7,8-hexahydropyrido[2,3-d]pyrimidin-5-yl)amino)benzoic acid (2b) (800 mg, 1.172 mmol) in THF (5 ml) was added EDC.HCl (494 mg, 2.58 mmol), HOBT (395 mg, 2.58 mmol), DIPEA (0.819 ml, 4.69 mmol) and pyrrolidin-3-ol hydrochloride (290 mg, 2.35 mmol). The reaction mixture was stirred at room temperature under N2 atm for 6 h. The reaction mixture was then partitioned between water and ethyl acetate. Organic phase was removed, washed with brine and dried over sodium sulphate. The solvent was evaporated in vacuop to afford crude 1-(2-fluoro-4-iodophenyl)-5-((3-(3-hydroxypyrrolidine-1-carbonyl)phenyl)amino)-3-(4-methoxybenzyl)-6,8-dimethylpyrido[2,3-d]pyrimidine-2,4,7(1H,3H,8H)-trione (2c) (550 mg) which was carried forward for the next step without further purification.
