Procedure

A solution of ethyl 2-(6-bromo-7-(4-(2-oxo-2-(thiazol-2-ylamino)ethyl)piperazin-1-yl)-3H-imidazo[4,5-b]pyridin-2-yl)cyclopropanecarboxylate (15 mg, 0.028 mmol) in ammonium hydroxide (2.5 mL) was heated in a sealed tube at 100° C. for 16 h. After this time, LC-MS analysis showed that only the desired product was present. Evaporation of the solvents in vacuo provided the product (9 mg, 64%) as a colourless solid; 1H-NMR (500 MHz, DMSO-d6) 1.40 (app. quintet, J=4.4 Hz, 1H, cyclopropane CHAHB), 1.46-1.51 (m, 1H, cyclopropane CHAHB), 2.20-2.24 (m, 1H, cyclopropane CH), 2.40 (br s, 1H, cyclopropane CH), 2.74 (t, J=4.9 Hz, 4H, piperazine N(CH2)2), 3.38 (s, 2H, NCH2CO), 3.54 (br s, 4H, piperazine N(CH2)2), 6.53 (d, J=3.7 Hz, 1H, thiazole H-4 or H-5), 6.83 (br s, 2H, NH2), 6.92 (d, J=3.7 Hz, 1H, thiazole H-4 or H-5), 7.02 (br s, 1H, CONH), 7.74 (br s, 1H, imidazo[4,5-b]pyridine H-5);
