In a medium bowl whisk together sugar, corn syrup, vanilla, salt and cinnamon. Add eggs and whisk until smooth.
In a small saucepan, melt butter and heat for about 4-5 minutes, until butter becomes brown and fragrant. Stir often. Pour butter into the sugar mixture and whisk to combine. Stir in pecans and pour into prepared crust.
Bake for 50-60 minute or until center is set. If your crust edges begin to get too brown, you can remove pie and cover crust with foil.
Cool pie on rack for 3-4 hours before slicing and serving.
