Procedure

To a solution of 4-(2,3-diphenyl-7,8-dihydropyrido[2,3-b]pyrazin-5(6H)-yl)butyl acetate (step 2) (410 mg, 1.021 mmol) in THF (6 ml) and water (3 ml) was added lithium hydroxide (56.9 mg, 2.375 mmol) and the mixture was heated at reflux for 18 h. The reaction mixture was diluted with EtOAc and the combined organic extracts were washed with water (2×), brine, dried (MgSO4), filtered and concentrated in vacuo to afford the title compound;
