Procedure
5-Fluorotoluidine (Example1,B), pyridine and pentyl nitrite are warmed until a vigorous reaction with evolution of gas sets in. This is allowed to proceed without heating until it has subsided (20 minutes) and the mixture is boiled under reflux for another 100 minutes. The excess pyridine is removed under reduced pressure to yield the title product.
