Reaction Steps

To a solution of 1-(trans-4-{[(5-nitro-2-{[2-(trifluoromethoxy)benzyl]amino}pyrimidin-4-yl)amino]methyl}cyclohexyl)azetidine-2-carboxylic acid (170 mg, 0.27 mmol) in DMF (1.5 mL) were added ammonium chloride (170 mg, 3.2 mmol), HATU (303 mg, 0.80 mmol) and DIPEA (370 μL, 2.1 mmol). The reaction mixture was stirred at room temperature for 16 h. The reaction mixture was diluted with EtOAc and washed with saturated NaHCO3, water (×3) and brine. The organic phase was dried over Na2SO4 and concentrated. The resulting residue was purified by silica gel preparative TLC using 95:5 CH2Cl2:MeOH as an eluent to afford 7 mg of the title compound, m/z 522.6 [M−1]+
