Procedure
To a solution of 1,2-diphenylethanone (392 mg, 2.0 mmol), 4-formylbenzoic acid (274 mg, 1.8 mmol) and urea (324 mg, 5.4 mmol) in EtOH (40 mL) was added concentrated HCl (0.17 mL). The mixture was stirred at 85° C. for 3 days. The volatiles were removed under reduced pressure and standard aqueous/EtOAc workup procedure was followed. Purification by inverse-phase column to afford Compound 90 as a tan powder (11 mg, 2%). 1H NMR (MeOH-d4 500 MHz TMS): δ 7.99 (d, J=7.0 Hz, 2H), 7.47 (d, J=7.0 Hz, 2H), 7.25 (s, 5H), 7.03 (s, 3H), 6.85 (s, 2H), 5.40 (s, 1H); MS (ESI): m/z 371.0 [M+1]+.
