Procedure

A mixture of 4-hydroxy-2-(pyridazin-3-yl)pyrimidine-5-carboxylic acid, 30-ie, (110 mg, 0.5 mmol), 2-(4-bromophenyl)propan-2-amine, 36-b, (70 mg, 0.32 mmol), HATU (290 mg, 0.76 mmol) and DIEA (82 mg, 0.64 mmol) in DMF (3 mL) was stirred at room temperature overnight. The mixture was washed with aqueous NH4Cl (15 mL) and extracted with EtOAc (30 mL). The organic layers were dried and concentrated in vacuo. The residue was washed with hexane to afford compound 36-c (80 mg, 57%). 1H NMR (300 MHz, CDCl3) δ11.62 (s, 1H), 9.55 (s, 1H), 9.41 (dd, J=1.5, 4.8 Hz, 1H), 9.00 (d, J=4.2 Hz, 1H), 8.63 (dd, J=1.5, 8.1 Hz, 1H), 7.78 (dd, J=5.1, 8.4 Hz, 1H)), 7.43 (d, J=8.4 Hz, 2H), 7.33 (d, J=8.4 Hz, 2H), 1.78 (s, 6H). LC-MS: (M+H)+ 414.
