Procedure

A solution of 404 mg (2.48 mmol) of 2-bromo-1-cyclopropylethanone in 15 ml of DMSO is added dropwise to 845 mg (2.48 mmol) of the crude mixture from Example 72A while cooling in ice, and the mixture is then heated at 100° C. for 1 h. The crude mixture is poured into ice-water and extracted three times with ethyl acetate. After the combined organic phases have been dried, the solvent is completely removed and the residue is purified by subsequent purification by preparative HPLC. 428 mg (48% of theory) of the product are obtained as a solid.
