Versuchsvorschrift

The alcohol 173 was prepared from 2.12 g (5.0 mmol) of 172 and 9.0 mL (9 mmol) of 120 in 50 mL of THF as described for the synthesis of 121 in Example 1. Flash chromatography (elution with 10% ethyl acetate in hexane) gave 3.3 g of the alcohol 173. 1H NMR consistent with the product.
