Procedure

A solution of (5-bromo-imidazo[1,2-a]pyrazin-8-yl)-[3-(tert-butyl-dimethyl-silanyloxymethyl)-4-morpholin-4-yl-phenyl]-carbamic acid tert-butyl ester (0.164 g, 0.265 mmol) in 1M tetrabutylammonium fluoride in THF (0.29 mL, 0.29 mmol) is stirred at room temperature overnight. The solvent is removed under vacuum and the residue is purified by silica gel column chromatography eluting with ethyl acetate. The title compound is isolated (0.126 g, 94%).
