1-Bromo-3-chloropropane → HCID 11609638, compound

Participants

Reaction Steps

The product of Example I, Step A (0.09 g) in acetone (2 mL) and DMF (2 mL) was treated with K2CO3 (0.2 g) followed by 1-bromo-3-chloropropane (0.11 g). The mixture was allowed to stir at rt for 16 h and was then partitioned between EtOAc (50 mL) and brine (50 mL). The organic layer was separated and washed with brine (2×200 mL), dried over Na2SO4, filtered, and evaporated to give the crude product. The crude product was purified by silica gel chromatography using 2-5% MeOH/CH2Cl2 as the eluent to provide (4-Chloro-phenyl)-[2-(3-chloro-propylsulfanyl)-3-methyl-3H-imidazol-4-yl]-methanol (0.08 g, 69%); M calc=330; M+H found=331.
