Reaction Steps

A mixture of 4-bromo-2-(2,6-dimethylmorpholin-4-yl)-5-nitrobenzaldehyde (from Step 2) (989 mg, 2.88 mmol) and barbituric acid (369 mg, 2.88 mmol) in isopropanol (15 mL) is sealed in a 20 mL scintillation vial and shaken at 85° C. for 2.5 hours. The product is adsorbed onto silica gel and purified by silica gel chromatography using a gradient from 20% EtOAc in CH2Cl2 to 25% EtOAc in CH2Cl2 as eluent. Product is isolated and dried (20 Torr, 100° C.) to give 512 mg of yellow solid. 1H NMR (DMSO-d6) δ 11.90, 11.62, 7.79, 7.36, 4.32, 3.87, 3.47-3.63, 2.94, 2.81, 1.15, 0.94.
