dodecanoyl dodecanoate

Conditions: temp:0.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a cooled mixture of Compound (1) (2.43 g.) and N-methylmorpholine (0.71 g.) in methylene chloride (40 ml.) was added dropwise isobutyl chloroformate (960 mg.) and the mixture was stirred for 20 minutes at 0° C. To this mixture was added a solution of Compound (2) (2.83 g.) in a mixture of methylene chloride (20 ml.) and dimethylformamide (10 ml.) containing bis(trimethylsilyl)acetamide (2 ml.). The reaction mixture was stirred for 2 hours and then concentrated to give an oily residue, which was dissolved in ethyl acetate, washed with water and dried over magnesium sulfate. Evaporation of the solvent gave a white foam, which was pulverized with isopropyl ether to give Compound (3) (4.20 g.) as white powder. The reaction mixture was stirred for 2 hours concentrated to give an oily residue, which washed with water dried over magnesium sulfate Evaporation of the solvent gave a white foam, which
