実験手順

HOBt (0.068 g, 0.50 mmol), EDCl.HCl (0.096 g, 0.50 mmol) and DIPEA (0.34 mL, 1.9 mmol) were added to a stirred solution of tert-butyl 4-(4-((4-(2-(2-methoxy-2-oxoethyl)phenethyl)-5-(trifluoromethyl)pyrimidin-2-yl)amino)benzoyl)piperazine-1-carboxylate (A25) (0.28 g, 0.39 mmol) in dry THF (6 mL) and dry DMF (1 mL) under an atmosphere of nitrogen. After 10 minutes ammonium carbonate (0.19 g, 1.9 mmol) was added in one portion and the resulting solution was stirred at room temperature for 17 hours. The volatiles were removed in vacuo and the residue was partitioned between EtOAc (65 mL) and saturated aqueous NaHCO3 (65 mL). The aqueous layer was extracted with EtOAc (2×50 mL) then the combined organic layers were washed with brine (50 mL) and dried over MgSO4. The volatiles were removed in vacuo and the residue was purified by silica gel column chromatography (Biotage Isolera, 25 g SiO2 cartridge, 0-100% EtOAc in petroleum benzine 40-60° C. then 0-20% MeOH in EtOAc) to give the title compound A26 as a white solid (0.18 g, 77%); 1H NMR (400 MHz, CDCl3) δ 8.58 (s, 1H), 7.91 (s, 1H), 7.72 (d, J=8.4 Hz, 2H), 7.44 (d, J=8.3 Hz, 2H), 7.31-7.21 (m, obscured), 5.43 (br. s, 2H), 3.74 (s, 2H), 3.71-3.35 (m, 8H), 3.18-3.03 (m, 4H), 1.47 (s, 9H). LCMS-A: rt 6.120 min; m/z 613.3 [M+H]+.
