Dimethylformamide → HCID 18463754, compound

Participants

Reaction Steps

Sodium hydride (60% in oil, 1.06 mmol, 42 mg) was washed with hexane (ca 2×1 ml), then covered with N,N-dimethyformamide (2.1 ml). 5-(3-Methylphenyl)-4-[4-(methylsulfonyl)phenyl]-2-trifluoromethyl-1H-imidazole (Example 59) (0.70 mmol, 268 mg) was added, with stirring. After 15 minutes, 2-(trimethylsilyl)ethoxymethyl chloride (SEM-Cl) (1.06 mmol, 0.19 ml) was added and the mixture was stirred overnight. The reaction was quenched with saturated ammonium chloride (ca. 4 drops), and concentrated in vacuo. The residue was subjected to chromatography (2:1 hexane: ethyl acetate) and concentrated to afford the title compound (284 mg, 79%) as an oil as a mixture of the two possible N alkylated isomers (by NMR).
