A mixture of 4-(1-methyl-1H-pyrrolo[3,2-b]pyridin-3-yl)aniline (70 mg) and 2-chlorobenzo[d]oxazole (57 mg) in 1-methylpyrrolidinone (2 mL) was stirred at 120° C. for 30 min. After this time, the reaction was cooled to room temperature, diluted with AcOEt (50 mL), washed with saturated NaHCO3 aqueous solution (50 mL), water (2×50 mL) then brine (50 mL), dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. The residue obtained was purified by silica gel column chromatography (CH2Cl2 to 1:19 MeOH/CH2Cl2), dissolved in 1,4-dioxane (2 ml), treated with 4 M HCl in 1,4-dioxane (0.500 mL, 2.00 mmol) and concentrated under reduced pressure. The residue obtained was triturated with boiling is CH3CN to give the title compound (60 mg).
