Reaction Conditions

Reaction Steps

Methyl 4-bromo-3-hydroxybenzoate (71 mg) and 4-(bromoacetyl)morpholine (71 mg) were combined in DMF (5 ml). Sodium hydride (14 mg, 60% dispersion in mineral oil) was added and the reaction heated at 80° C. under nitrogen for 16 hours. The reaction was quenched with water (2 ml) and solvent the evaporated in vacuo. The residue was partitioned between water (10 ml) and ethyl acetate/chloroform (1:1, 2×10 ml). The organic layers were combined, dried using a hydrophobic filter and evaporated under vacuum. The residue was partially purified by SPE (2 g, Si), eluting with a methanol/chloroform gradient (0.5% to 5%), and the product fractions further purified by mdap, to give methyl 4bromo-3{[2-(4-morpholinyl)-2-oxoethyl]oxy}benzoate as a white solid (16 mg).
