Reaction Steps

A 2L high-pressure vessel was charged with Palladium 10% on carbon wet (50% water) and EtOAc (50 mL). 2-methyl-5-nitro-N-(pyrimidin-5-yl)benzamide 45 (18.79 g) was dissolved in methanol (400 mL) and added to the previous mixture. The reaction vessel was pressurized to 30 psi of H2 and mechanically stirred until the hydrogen intake stopped. The reduction of the nitro group was complete by LCMS and the mixture was filtered off through paper and glass paper. The crude 5-amino-2-methyl-N-(pyrimidin-5-yl)benzamide 46 was obtained as a yellow solid and used without further purification.
