Reaction Steps
1-(2,2-difluoro-1,3-benzodioxol-5-yl)-cyclopropanecarboxylic acid (1.2 eq) is slurried in toluene (2.5 vol) and the mixture heated to 60° C. SOCl2 (1.4 eq) is added via addition funnel. The toluene and SOCl2 are distilled from the reaction mixture after 30 minutes. Additional toluene (2.5 vol) is added and distilled again.
