Conditions

Temperature: 25 °C

Procedure

Oxalyl chloride (46.5 g, 0.367 mol, Aldrich) was added to a solution of 3-(4-fluorophenyl)-3-methylbutyric acid (24 g, 0.122 mol) at -10° C. while protected from moisture by a nitrogen atmosphere. The stirring mixture was allowed to warm to 25° C. and was stirred for 2 h. Fractional distillation gave 26.6 g (76%) of 3-(4-fluorophenyl)-3-methylbutyryl chloride as a clear oil, b.p., 132°-138° C.;
