Procedure
To a solution of (R)-4-(2,4-dimethoxybenzylamino)-3-(4-(6-fluorochroman-4-ylamino)-5-nitropyrimidin-2-ylamino)benzonitrile (prepared as described below in example 26, paragraph [0157]) (12 mg) in THF (5 mL) was added a premixed solution of sodium hydrosulfite (100 mg) and sodium bicarbonate (50 mg) in water (10 mL). MeOH (1 mL) was also added to aid solution of the mixture, which was stirred at room temperature for 30 min, when sodium chloride was added to saturate the solution. The resultant mixture was extracted with EtOAc (2×), the combined organics were dried, filtered and evaporated to yield (R)-4-(2,4-dimethoxybenzylamino)-3-(5-amino-4-(6-fluorochroman-4-ylamino)pyrimidin-2-ylamino)benzonitrile that was used as such for the next step, MH+=542.
