Procedure

A solution of 4-chloro-2-ethoxyimidazole-5-carboxaldehyde (295.0 mg, 1.7 mmol), 4′-bromomethyl-3′-fluorobiphenyl-2-carboxylic acid t-butyl ester (617 mg, 1.7 mmol) and potassium carbonate (467 mg, 3.4 mmol) in DMF (6 mL) was stirred overnight. The mixture was filtered and concentrated in vacuo. Silica gel chromatography (hexane:EtOAc) afforded intermediate (27a) (598 mg).

Workup

  1. filtrationThe mixture was filtered
  2. concentrationconcentrated in vacuo
