Procedure
Step 2—Synthesis of compound un: (S)-3-ethoxy-4-(4-(4-(3-methylmorpholino)-7-(pyrimidin-2-yl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-2-yl)phenylamino)cyclobut-3-ene-1,2-dione (0.087 g, 0.00016 mol), Ethylamine Hydrochloride (0.0780 g, 0.000956 mol), and Ethanol (8.00 mL, 0.137 mol) were combined then added Triethylamine (0.230 mL, 0.00165 mol) and stirred overnight. The reaction mixture was concentrated, and chromatographed through silica gel (12 g, 0-5% MeOH in dichloromethane). 1H NMR (400 MHz, DMSO) δ 9.83 (s, 1H), 8.44 (d, J=4.7, 2H), 8.31 (d, J=8.7, 2H), 7.72 (s, 1H), 7.53 (d, J=8.5, 2H), 6.69 (t, J=4.7, 1H), 4.90 (d, J=18.7, 1H), 4.75 (d, J=18.6, 1H), 4.14 (t, J=9.3, 2H), 3.85 (dd, J=20.6, 7.2, 2H), 3.74-3.55 (m, 6H), 3.44 (t, J=11.9, 1H), 2.75 (s, 2H), 1.31-1.15 (m, 6H). LC/MS-m/z+527.3 (M+H)+.
