To a stirred suspension of 314 mg (0.85 mmol) N-[7-methoxy-4-(tetrahydro-pyran-4-yl)-thiazolo[5,4-c]pyridin-2-yl]-benzamide in 2.5 ml methanol was added 0.85 ml 5 N aq. sodium hydroxide solution and the resulting solution was then heated at 130° C. for 12 min in a microwave oven. The reaction mixture was then cooled to room temperature and partitioned between tetrahydrofuran and 1 N aq. sodium hydroxide solution. The phases were separated and the organic phase was dried over sodium sulfate and concentrated in vacuo. Flash chromatography (methanol/dichloromethane) afforded 174 mg (77%) 7-methoxy-4-(tetrahydro-pyran-4-yl)-thiazolo[5,4-c]pyridin-2-ylamine as a light yellow crystalline solid. ES-MS m/e (%): 266 (M+H+, 100).
