Procedure

To a solution of ethyl 4-hydroxy-5-methylpyrrolo[2,1-f][1,2,4]triazine-6-carboxylate (442 mg, 2.0 mmol) (see example 6 of US Pat. App. 2003/0186982, the disclosure of which is herein incorporated by reference ) in 10 mL of THF was added a solution of NaOH (1 N, 6.0 mL). The mixture was heated at 60° C. overnight and HPLC analysis indicated the completion of the reaction. After cooling down, the solution was neutralized with 6.0 mL of 1 N HCl. The organic solvent was then removed and the solid was collected after filtration to the title compound (350 mg, 91%). MS(ESI+) m/z 194.2 (M+H)+.
