Reaction Steps

To a solution of N4-[(trans-4-aminocyclohexyl)methyl]-N2-[5-chloro-2-(trifluoromethoxy)benzyl]-5-nitropyrimidine-2,4-diamine (51 mg, 0.1 mmol) in DMF (0.5 mL) was added 1,4-dibromobutane (36 μL, 0.3 mmol) and DIPEA (104 μL, 0.6 mmol). The reaction mixture was stirred at 50° C. for 24 h and then 72 h at room temperature. The reaction mixture was then partitioned between EtOAc (20 mL) and saturated NaHCO3 (less than 1 mL). The organic phase was washed with water (2×2 mL) and dried over Na2SO4. The resulting residue was purified by preparative HPLC to afford 13 mg (25%) of the title compound as a yellow oily solid, m/z 529.3 [M+1]+
