I-a) Ciclización del yoduro (5a):
A una mezcla de yodo (5a) y vinilboronato de pinacol (6, 1,3 equiv.) en DMF se añadió LiOH (3 equiv.) seguido de PdCl2(dppf)·CH2Cl2 (3% molar) bajo una atmósfera inerte (Ar). La mezcla de reacción se calentó a 70ºC y se agitó
10 durante 18 h. El análisis de HPLC indicó una conversión completa en el éter vinílico "Intermediario A" (EM: (Turbo pulverización) 277 (33%), 275 (M+H+, 100%), 231 (22%), 229 (84%), 205 (11%)). Tras enfriar a 50ºC, se añadió HCl al 25% (15 equiv.). La mezcla se mantuvo a dicha temperatura durante 1 h. Tras el tratamiento final se aisló el azaindol 8 en forma de un sólido cristalino con un rendimiento de 92%. EM (Turbo pulverización): 231 (26%), 229 (M+H+, 100%).

I-b) Ciclización del bromuro:
A una mezcla de bromo (5b) y vinilboronato de pinacol (6, 1,2 equiv.) en DMF se añadió LiOH (3 equiv.) seguido de PdCl2(dppf)·CH2Cl2 (3% molar). La mezcla de reacción se calentó a 70ºC y se agitó durante 18 h. El análisis de
20 HPLC indicó una conversión completa en el intermediario éter vinílico. Tras enfriar la mezcla de reacción a 50ºC, se añadió HCl (al 25%) y la mezcla se agitó a dicha temperatura durante 1 h.
