실험 절차

A mixture of trans-4-(4-benzotriazol-1-yl-5-chloro-pyrimidin-2-ylamino)-cyclohexane-carboxylic acid (70 mg, 0.17 mmol), ethyl amine (21 μL, 0.26 mmol), BOP (114 mg, 0.26 mmol) and DIPEA (59 μL, 0.34 mmol) in THF (60 mL) was stirred at RT for 2 days. The white solid formed was removed by filtration and the filtrate was diluted with water (25 mL) and extracted 3 times with a mixture isopropanol/chloroform (1/1, 20 mL). The combined organic extracts were dried over Na2SO4, filtered and evaporated under reduced pressure to give an off white residue that was purified via flash chromatography (DCM/MeOH, 98/2) to afford 68 mg (quantitative yield) of trans-4-(4-benzotriazol-1-yl-5-chloro-pyrimidin-2-ylamino)-cyclohexane-carboxylic acid ethylamide as a white solid. MS: 400.17 (M+1)+, 372.17 ((M+1)+−28). 1H NMR (250 MHz, CD3OD) δ ppm: 8.55 (1 H, s), 8.09-8.21 (2 H, m), 7.69 (1 H, dd, J=7.50 Hz), 7.55 (1 H, dd, J=7.50 Hz), 3.71-3.88 (1 H, m), 3.18 (2 H, q, J=7.29 Hz), 2.10-2.25 (3 H, m), 1.82-1.95 (2 H, m), 1.50-1.71 (2 H, m), 1.26-1.48 (2 H, m), 1.10 (3 H, t, J=7.29 Hz).
