Reaction Steps

To a suspension of N1-[4-[2-(difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-N3,N3-dimethyl-N1-[1-(methylsulfonyl)-3-piperidinyl]-1,3-propanediamine from the previous step in MeOH (20 mL) was added a slight excess of 1.25 M HCl in MeOH (0.18 mL) to give a clear solution. The solvent was removed under vacuum and the residue was washed with EtOAc to give N1-[4-[2-(Difluoromethyl)-4-methoxy-1H-benzimidazol-1-yl]-6-(4-morpholinyl)-1,3,5-triazin-2-yl]-N3,N3-dimethyl-N1-[1-(methylsulfonyl)-3-piperidinyl]-1,3-propanediamine hydrochloride: mp (MeOH/EtOAc/hexanes) 189° C.
