Methyl iodide → 1-Benzhydryl-3-methyl-5-phenyl-pyrimidine-2,4-dione

Participants

Reaction Steps

The title compound was obtained according to the procedure described for the synthesis of Example 16 (Step 1) starting from 1-benzhydryl-5-phenyl-pyrimidine-2,4-dione (prepared as in Example 14, Step 2) (0.37 g, 1.01 mmol); a 1:1 mixture of was dry MeCN/THF and iodomethane were used herein. The crude was purified by column chromatography using a Teledyne ISCO apparatus (cyclohexane:EtOAc 80:20) to afford the title compound (0.16 g, 43%) as a light-red solid. 1H NMR (400 MHz, CDCl3): δ 3.46 (s, 3H), 7.19-7.24 (m, 6H), 7.28-7.43 (m, 11H). MS (ESI) m/z: 369 [m-H]+.
