Reaction Steps

To a suspension of N-{3-[5-(2-cyano-4-pyrimidinyl)-2-(4-morpholinyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-2,5-difluorobenzenesulfonamide (2.12 g, 3.80 mmol) in dichloromethane (DCM) (38.0 ml) at −78° C. was added DI BAL-H (18.98 ml, 18.98 mmol). The yellow suspension was slowly warmed to RT and stirred 1 hr. The reaction was quenched with Rochelle's salts and stirred about 1 hr. 4N HCl was added to clear the emulsion. The HCl solution was extracted with DCM (3×). The aqueous was passed through celite and neutralize with 6N NaOH. Solid formed during neutralizing and was filtered to obtain N-{3-[5-[2-(aminomethyl)-4-pyrimidinyl]-2-(4-morpholinyl)-1,3-thiazol-4-yl]-2-fluorophenyl}-2,5-difluorobenzenesulfonamide (1.57 g, 73%). MS (ESI): 563 [M+H]+.
