Imidazole → HCID 66702002, compound

Participants

Reaction Steps

Imidazole (1.2 g) was added to a solution of tert-butyldimethylsilyl chloride (2.83 g) and the subtitle product of step iii) (1.8 g) in DMF (10 ml). The reaction was stirred for 20 h before partitioning between EtOAc (100 ml) and H2O (200 ml). The aqueous was extracted further with EtOAc (2×100 ml), the organics combined, washed with H2O (100 ml), brine (100 ml), dried (MgSO4) and concentrated in vacuo to a crude solid. This material was purified by column chromatography (50% Et2O/iso-hexane) to afford the subtitle compound as a yellow oil. Yield: 1.80 g.
