Participants

Reaction Steps

2.48 g of rac-8-[(2,6-difluorobenzyl)oxy]-2-methyl-N-(4,4,4-trifluoro-1-hydroxybutan-2-yl)-imidazo-[1,2-a]pyridine-3-carboxamide (Example 34A, 5.59 mmol) were initially charged in dichloromethane. At 0° C., 1.22 ml of thionyl chloride (16.77 mmol) were added dropwise, and the mixture was stirred at RT overnight. The reaction solution was concentrated and dried under high vacuum. This gave 2.78 g of the title compound (99.8% of theory).
