Yield: 70%
Reaction Conditions:
in 1-methyl-pyrrolidin-2-one for 4 h;Reflux;
Steps:
11 3-Benzyloxy-4H-pyran-4-one (14b)
5-Benzyloxy-4-oxo-4H-pyran-2-carboxylic acid (13b) (15.87 g, 64.5 mmol) and 1-methyl-2- pyrrolidinone (160 mL) were refluxed for 4 h.
Then the solvent was removed azeotropically with N,N-dimethylformamide (160 mL) in high vacuum.
The residue was extracted into dichloromethane and washed with 5% aqueous sodium hydroxide (3 * 90 mL).
The organic layer was dried over Na2SO4, concentrated and recrystallized from toluene to give a pale yellow solid (14b) (9.07 g, 70%).
