To a mixture of allyl alcohol (22.1 g, 380.5 mmol) and triethylamine (Et3N) (5.4 ml, 39 mmol) at 0° C. was added over 1 h crude (5-bromo-2-fluoro-phenyl) -acetyl chloride (intermediate B2A) (7.01 g, ca. 26 mmol). Then the reaction was stirred over 1 h from 0° C. to 23° C. The reaction mixture was diluted with ethyl acetate, washed with water, and the organic layer was dried over sodium sulfate. Removal of the solvent in vacuum left the title compound as a yellow oil (7.290 g, 103%), which was used without further purification. MS (ISP): m/z=280.1 [(M+NH4)+] and 282.1 [(M+2+NH4)+]
