Reaction Steps

TEA (52 μL, 0.37 mmol) was added, under nitrogen atmosphere, to a solution of trans-(4-aminomethyl-cyclohexyl)-(4-benzotriazol-1-yl-pyrimidin-2-yl)-amine (60 mg, 0.185 mmol) in DCM (3 mL). The mixture was cooled to −78° C. and acetyl chloride (13.2 μL, 0.185 mmol) was added. The reaction mixture was stirred at RT overnight; it was then poured in water and extracted 3 times with a mixture of isopropanol and chloroform. The combined organic extracts were dried over Na2SO4, filtered and the solvent was evaporated under reduced pressure. The crude residue was purified via preparative TLC to give 10 mg of trans-N-[4-(4-benzotriazol-1-yl-pyrimidin-2-ylamino)-cyclohexylmethyl]-acetamide. 1H NMR (400 MHz, CDCl3) δ ppm 8.55 (1 H, d, J=8.19 Hz), 8.41 (1 H, d, J=5.14 Hz), 8.12 (1 H, d, J=8.19 Hz), 7.57-7.67 (1 H, m), 7.42-7.51 (2 H, m), 7.16-7.24 (0.3 H, m), 5.55-5.64 (0.7 H, m), 5.18-5.43 (1 H, m), 3.80-3.93 (1 H, m), 3.11-3.25 (2 H, m), 2.27 (1 H, s), 2.19-2.35 (2 H, m), 2.00 (2 H, s), 1.85-1.95 (2 H, m), 1.50-1.63 (1 H, m), 1.11-1.37 (4 H, m).
