Reaction Steps

The title compound was prepared in an analogous fashion to that described infashion to that described in Example 185 using (R)-5-bromo-N-(4-((chlorodifluoromethyl)thio)phenyl)-6-(3-hydroxypyrrolidin-1-yl)nicotinamide (Stage 217.1) and 3-fluoro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine to afford an off-white foam.
