| Product | 2,2-Dimethyl-propionic acid 2,3-bis-(2,2-dimethyl-propionyloxy)-6-[3,4,5-tris-(2,2-dimethyl-propionyloxy)-benzoyl]-phenyl ester | HCID 14010408 | — |
Reaction Steps
100 mg of 3,4,5,4',5',6'-hexahydroxy benzophenone (0.00036 mole) and 450 MG (0.004 mole) of pivaloyl chloride were warmed to 50° C. in 20 mls of pyridine for 4 hrs. Solvent removed via N2 stream. Water added and extraction of product was done via CH2Cl2. The organic layer was washed with K2CO3 (5%) and dried over MgSo4. Solvent removal left an oil. 250 mg. (88%) yield.
