Procedure

27.8 g (0.146 mol) of 18b in 500 ml of THF are treated with 365.4 ml (0.438 mol) of DIBAL (20% strength solution in toluene) at -70° C. overnight in analogy to Example 1a. The crude product is vigorously stirred in boiling ethyl acetate and, after cooling to 20° C., the remaining material is filtered off with suction.
