Reagents, catalysts & solvents 1

HCID 6422Trifluoroacetic acidSolvent

Procedure

In 15 ml of trifluoroacetic acid was dissolved 1.76 g of Compound (44). After 1 hour, the solution was concentrated under reduced pressure. To the residue was added 100 ml of water, and the mixture was washed with benzene. The aqueous layer was adjusted to a pH of 12 with sodium hydroxide and extracted with chloroform. The organic layer was dried over anhydrous sodium sulfate, and the solvent was evaporated to obtain the titled compound (45) as a colorless oil.
