Reaction Steps

This compound was prepared from the products of 8a (0.73 g; 2.7 mmol) and 8b (1.0 g; 2.5 mmol) according to Procedure C. The crude product was purified on a 75×45 mm silica gel 60 column eluted with ethyl acetate-hexane (1:1) (1000 mL) collecting 13×50 mL fractions. Fractions containing the product (5-8) were collected, and after evaporation 0.82 g (72%) product was obtained (yellowish solid, mp 53-56° C.).
