Reaction Steps
2.9 g. of the product from Example 80 is dissolved in a mixture of trifluoroacetic acid (17.5 ml.) and anisole (8.4 ml.). After one hour storage at room temperature, the excess trifluoroacetic acid is removed in vacuo and the residue is precipitated twice from ether-hexane to yield 2.1 g. of the named product. Rf : 0.4 (silica gel-benzene:acetic acid, 75:25).
