Lithium iodide → HCID 67954838, compound

Participants

Reaction Steps

To a stirred solution of ethyl 1,6-dihydro-6-oxo-2-phenyl-1-(phenylmethyl)-5-pyrimidinecarboxylate (i.e. the product from Step B) (2.9 g, 8.6 mmol) in pyridine (15 mL) was added lithium iodide (3.01 g, 21.7 mmol). The reaction mixture was heated to reflux for 4 h, cooled, and then stirred at room temperature for 72 h. The reaction mixture was concentrated under reduced pressure. To the resulting residue was added water (10 mL), followed by 1 N hydrochloric acid until the pH was 7. The solution was filtered through Celite® diatomaceous filter aid, and the filtrate was acidified with 1 N hydrochloric acid until the pH was 1. The mixture was extracted with dichloromethane, and the organic layer was dried (MgSO4) and concentrated under reduced pressure to afford a solid, which was washed with diethyl ether and dried under reduced pressure to afford the title product as a white solid (2.2 g).
