Reaction Steps

A solution containing 4.43 g. (0.016 mole) of 2-(4-methylphenyl)-5-benzoxazolecarbonyl chloride in 50 ml. of methylene chloride was added dropwise to a solution containing 1.88 g. (0.02 mole) of phenol and 0.80 g. (0.02 mole) of sodium hydroxide in 25 ml. of water. After stirring at 50° for 20 hours, the layers were separated and the organic layer was dried (MgSO4) and concentrated to give 2.9 g. (54%) of ld: UV (CH2Cl2) λmax 306 nm (18,200), ε325 =3500.
