Procedure

2-(cis-2-methyl-6-propylmorpholin-4-yl)-5-nitrobenzaldehyde (446 mg, 1.53 mol) is combined with barbituric acid (217 mg, 1.53 mmol, Aldrich) in a vial with MeOH (6 mL). The sealed reaction is heated to 80° C. on a shaker block for 19 hours and then the solvent is removed by rotary evaporation. The product is purified 2× on a Biotage Flash 75M using 10% MTBE in CH2Cl2 eluent. The product is dried under vacuum at 100° C. yielding a yellow-orange solid. 1H NMR (400 MHz, ACETONITRILE-D3) δ ppm 0.95, 1.00, 1.47, 3.04, 3.34, 3.56, 3.95, 4.14, 6.85, 7.77, 8.02, 9.19.
