Reaction Steps

A solution fo oxalyl chloride (2.8 ml) in 20 ml of CH2Cl2 is treated with a solution of dimethyl sulfoxide (DMSO)(5.0 ml) in 15 ml of CH2Cl2 at -60° C. as in Example 11 To this mixture is added the 3-trifluoromethyl-5-methylbenzyl alcohol (5.4 g) in CH2Cl2 (20 ml) followed by 20 ml of triethlyamine. Appropriate reaction conditions and work-up as in Example 11 afforded 3-trifluoro- methyl-5-methylbenzaldehyde.
