Procedure

To a solution of 3-[5-(2-ethylbenzoimidazol-1-yl)-7-morpholin-4-ylthiazolo[5,4-d]pyrimidin-2-ylmethylene]azetidine-1-carboxylic acid tert-butyl ester (493 g, 0.92 mmol) in AcOH (20 mL) was added 10% Pd(OH)2/C (200 mg) and the resulting mixture stirred under an atmosphere of H2 for 2 h. The reaction mixture was filtered through Celite®, washing with EtOAc. The filtrate was loaded onto an Isolute® SCX-2 cartridge which was washed with MeOH and the product eluted with 2M NH3/MeOH affording the title compound.
