Procedure

4-[2,4-Bis-((S)-3-methyl-morpholin-4-yl)-pyrido[2,3-d]pyrimidin-7-yl]-2-methoxy-benzoic acid (1 equiv) was dissolved in THF (0.1 M) and HBTU (1.5 equiv) was added. Methylamine in THF (15 equiv) was added dropwise followed by triethylamine (1.5 equiv) and the reaction mixture was stirred at room temperature for 2 hours. The reaction mixture was concentrated in vacuo. The residue was partitioned between water and CH2Cl2. The aqueous phase was extracted with CH2Cl2. Combined organic phases were dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified by preparative HPLC to give the desired product.
