A solution of phenylmethyl{2-[(2-amino-5-bromopyridin-3-yl)amino]-2-oxoethyl}methylcarbamate (0.30 g, 0.76 mmol) in acetic acid (7.5 mL) was heated in a microwave apparatus (250 W) for 30 min. at 120° C. After cooling it to room temperature the reaction mixture was concentrated and the pH was adjusted to 8 by the addition of saturated aqueous sodium bicarbonate. The precipitating solid was collected by filtration, washed with water and dried in vacuo to give phenylmethyl[(6-bromo-1H-imidazo[4,5-b]pyridin-2-yl)methyl]methylcarbamate (0.22 g, 76%). MS (EI) for C16H15BrN4O2: 376 (MH+).
