Procedure

Prepared according to procedure L using 6′-bromo-1′,2,2′,3,5,6-hexahydrospiro-[pyran-4,3′-pyrrolo[3,2-b]pyridine] (89 mg, 0.33 mmol), 4-chloro-7-fluoro-3-methyl-2-(pyridin-2-yl)quinoline (90 mg, 0.33 mmol) and hydrochloric acid in 1,4-dioxane (83 μL, 0.330 mmol) in NMP (2.0 mL) and heating in the microwave at 150° C. for 2 h. After purification 6′-bromo-1′-(7-fluoro-3-methyl-2-(pyridin-2-yl)quinolin-4-yl)-1′,2,2′,3,5,6-hexahydrospiro[pyran-4,3′-pyrrolo[3,2-b]pyridine] was obtained as a yellow film. Mass Spectrum (ESI) m/e=505 [(M+1) (79Br)] and 507 [(M+1) (81Br)].
