Participants

Reaction Steps

Using the procedure outlined in Example 28 Step F, the title compound was prepared from N′,N′-dimethyl-propane-1,3-diamine and 8-cyclohexyl-2-methanesulfonyl-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester (Example 35 Step E, 20 mg, 0.05 mmol). 8-Cyclohexyl-2-(3-dimethylamino-propylamino)-5-oxo-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid ethyl ester was obtained as a white solid (17 mg, 85%). Mass Spectrum (LCMS, ESI pos.) Calcd. For C21H31N5O3: 402.24 (M+H). Found: 402.2.
