    摘要: The invention provides a process for the production of a compound of formula I, which comprises reacting a compound of formula II with a compound of formula III, in the presence of a strong base and a palladium(0) catalyst, at an elevated temperature, in a solvent which does not adversely affect the reaction. Compounds of formula I may be further processed to compounds of formula V, which are useful in the treatment of inter alia migraine.
