실험 절차

7-((R)-1-((R)-5-oxopyrrolidin-3-yl)ethoxy)benzo[d]thiazol-5-yl trifluoromethanesulfonate (4.04) (100.7 mg, 0.245 mmol), tert-butyl 4-(2-methoxy-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)piperazine-1-carboxylate 7.08 (144 mg, 0.344 mmol), Pd(OAc)2 (2.8 mg, 0.012 mmol), 2-Dicyclohexylphosphino-2′,4′,6′-triisopropylbiphenyl (12 mg 0.025 mmol), and K3PO4 (155 mg, 0.73 mmol) were taken up in THF (3.6 mL) under Ar. Water (0.36 mL) was added and the resulting stirred mixture was heated to 65° C. After 1.25 h, the reaction mixture was cooled and was partitioned between EtOAc, water, and brine. The phases were separated, and the aqueous phase was extracted with EtOAc. The combined organic phase was dried over Na2SO4, filtered, and concentrated. The crude residue was purified by silica gel chromatography to afford tert-butyl 4-(2-methoxy-4-(7-((R)-1-((R)-5-oxopyrrolidin-3-yl)ethoxy)benzo[d]thiazol-5-yl)phenyl)piperazine-1-carboxylate. LCMS-ESI+ (m/z): [M+H]+ calcd for C29H37N4O5S: 553.3; found: 552.8.
