실험 절차
As shown in step 6-ii of Scheme 6, to compound 1013 (1.2 g, 4.41 mmol) in DCM (20 mL) was added TEA (1.134 g, 1.84 mL, 13.2 mmol) and MsCl (505 mg, 341 μL, 4.41 mmol). The reaction mixture was stirred for 1 hour, concentrated under reduced pressure, and purified by medium pressure silica gel chromatography (0 to 80% EtOAc/hexanes gradient) to provide trans-4-((5-bromopyrimidin-2-yl)amino)cyclohexyl methanesulfonate (compound 1014): 1H-NMR (300 MHz, CDCl3) δ 8.29 (s, 2H), 5.03 (d, J=7.8 Hz, 1H), 4.70 (tt, J=10.6, 3.9 Hz, 1H), 3.80 (dtt, J=11.2, 7.6, 3.7 Hz, 1H), 3.04 (s, 3H), 2.30-2.12 (m, 4H), 1.93-1.69 (m, 2H), 1.51-1.33 (m, 2H).
