Reaktionsschritte
A mixture of the title C compound, [4-(5-methyl-2-phenyl-oxazol-4-ylmethoxy)-phenyl]-methanol (1.5 g, 5.08 mmol), carbon tetrabromide (2.53 g, 7.62 mmol), and triphenylphosphine (2.0 g, 7.62 mmol) in DCM is stirred at RT overnight. The mixture is then concentrated under vacuum, and chromatographed on a silica gel column using 8% EtOAc in hexane as the eluent to give 4-(4-bromomethyl-phenoxymethyl)-5-methyl-2-phenyl-oxazole as a white solid.
