Reaction Steps

A solution of the product of Example 46 (18.8 mg, 0.05 mmol), NMP (5 mL) and N,N-diethylethylenediamine (28 mg, 0.25 mmol, 5 eq) was heated to 50°. After 1 h, H2O (20 mL) was added and then EtOAc (20 mL). The layers were separated. The organic layer was washed with satd aq NaCl, dried (MgSO4) filtered and the solvent was evaporated in vacuo. The yellow residue was purified by Flash chromatography to afford 2-(2-diethylamino-ethylamino)-4,8-diphenyl-8H-pyrido[2,3-d]pyrimidin-7-one (21 mg, 89% yield). 1H-NMR (CDCl3) δ 0.74-0.98 (m, 6H), 2.28-2.56 (m, 8H), 2.98 (br s, 1H), 6.32 (d, 1H, J=9.8 Hz), 7.26 (m, 2H), 7.09-7.88 (m, 1H), LC MS (m/e)=414 (MH+).
