Participants

Reaction Steps

The NaOH extracts from the product of Example 7 were brought to pH 2 with dilute HCl and extracted with ether. These extracts were dried (Na2SO4), evaporated and the yellow glass dried at 30° centigrade/0.5 mm. yielding 18.4 g (46%) of the title compound. A 0 28 g-sample prepared in this manner was flash chromatographed on a 1×15 cm column of silica gel in 20% C2H5OCOCH3 --CH2Cl2 and furnished 0.13 g of the title compound.
