Reaction Steps

0.035 g 1-[3-Methoxymethyl-2-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-3H-imidazo[4,5-b]pyridin-5-yl]-piperidin-4-ol (0.07 mmol) was treated with 5N HCl (1 ml) at 90° C. for 0.5 h. The reaction mixture was concentrated, taken up in water (1 ml) and adjusted to pH 10 with ammonium hydroxide (25%), whereupon a precipitation formed. The precipitation was filtered and the crystals were triturated in hot ethanol. After drying in vacuo 0.018 g 1-[2-(4-methoxy-7-morpholin-4-yl-benzothiazol-2-yl)-3H-imidazo[4,5-b]pyridin-5-yl]-piperidin-4-ol (56%) was obtained as a yellow solid; M.p.: 228–230° C.
