Reaction Steps

To a solution of [2-(4-acetamido-phenylsulfanyl)-7-nitroquinazolin-4-yl]-(5-methyl-2H-pyrazol-3-yl)-amine (147 mg, 3.38.10−4 mol) in methanol (5 mL) is added Pd/C 10% (40 mg) and the reaction mixture is treated with hydrogen at balloon pressure at 45° C. for 20 hours. The catalyst is filtered through a pad of celite which is then washed with dilute HCl. The combined yellow filtrate is evaporated and the resulting solid residue is crystallized from methanol to afford the desired [2-(4-acetamido-phenylsulfanyl)-7-hydroxyaminoquinazolin-4-yl]-(5-methyl-2H-pyrazol-3-yl)-amine.
