Infrared spectrum exhibited typical pattern of ε-N-mono-substituted lysine derivative: 1580-1590 cm-1 (ionized carboxyl group), 1635 and 1520-1535 (amide bands). The compound was further purified by washing with ethanol and crystallizing from glacial acetic acid giving 2.08 g (84%) of the pure title compound.

Procedure:
Oxone® (566 mg, 0.93 mmole) is added to a solution of the compound of Example 2 (200 mg, 0.31 mmole) in THF (6 ml). The reaction mixture is completed with water (3 ml) and stirred at 23° C. for 3 h 30, the time necessary for the total conversion of the starting product. The mixture is then poured into water (25 ml) and extracted with AcOEt (2×25 ml). After decantation, the organic phases are combined and washed with salt water (20 ml), dried over Na2SO4, filtered and concentrated to dryness under vacuum. The evaporation residue is purified on a silica column (eluent: Heptane/AcOEt: 1/1 to 3/7). The expected compound is obtained in the form of a colourless oil with a yield of 89% (185 mg).

Procedure:
2-Amino-5-bromo-3-nitropyridine (218 mg) and 4-(1,3-oxazol-5-yl)benzaldehyde (173 mg) were suspended in dimethylsulfoxide (2 mL), followed by stirring at 80° C. for 20 minutes. Ethanol (4 mL) and 1M aqueous sodium hydrosulfite solution (3 mL) were added to the solution, followed by refluxing under heating for 15 hours. After the reaction mixture had been left to cool, water (20 mL) and concentrated aqueous ammonia solution (500 μL) were added thereto, and the precipitated solid was recovered through filtration, followed by washing with water and drying under reduced pressure, to thereby yield a 1:1 mixture (258 mg) of 5-[4-(6-bromo-3H-imidazo[4,5-b]pyridin-2-yl)phenyl]-1,3-oxazole and 5-[4-(6-bromo-1H-imidazo[4,5-b]pyridin-2-yl)phenyl]-1,3-oxazole.
