Reaction Conditions

Reaction Steps

2-(cis-2,6-Diethylmorpholin-4-yl)-5-nitrobenzaldehyde (1.58 g, 5.39 mmol) is combined with barbituric acid (767 mg, 5.39 mmol, Aldrich) in a flask with MeOH (17 mL). The sealed reaction is stirred with heating at 80° C. overnight. The solvent is removed by rotary evaporation and the product is purified on a Biotage Flash 40M+ using a 10% MTBE in CH2Cl2 as eluent. The product is dried under vacuum and re-crystallized from CH3OH/heptane. The large crystals are crushed and dried under vacuum @ 100° C. yielding 1.04 g (48%) of bright yellow crystalline solid. 1H NMR (400 MHz, DMSO-d6) δ ppm 0.86, 0.97, 1.08, 1.24, 1.45, 1.58, 2.84, 3.03, 3.34, 3.60, 3.97, 4.26, 7.01, 7.84, 7.98, 11.56, 11.87.
