Procedure

A solution of 4-[2,4-bis-((S)-3-methyl-morpholin-4-yl)-pyrido[2,3-d]pyrimidin-7-yl]-2-methoxy-benzoic acid methyl ester (1 equiv) in ethylenediamine (0.35 M) was stirred at room temperature for 24 hours. DMA was added to the solution (ethylenediamine/DMA 1:1.25). The reaction vessel was sealed and exposed to microwave radiation (180° C., medium absorption setting) for 1 hour. The reaction mixture was diluted with CH2Cl2 and extracted with water and washed with brine. The organic layer was dried with magnesium sulphate, filtered and concentrated in vacuo to yield a yellow solid which was then purified by preparative HPLC to give the desired product.
