실험 절차

The procedure as in Example 1: step c was followed using [3-Methyl-2-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzyloxy]-acetic acid tert-butyl ester (252.2 mg, 0.62 mmol, Example 131: step d), {[4-(5-Bromo-pyridine-3-sulfonyl)-5-methylsulfanyl-thiophen-2-yl]-imino-methyl}-carbamic acid tert-butyl ester (75.9 mg, 0.15 mmol, Example 128: step a), Pd(PPh3)4 (35 mg, 0.03 mmol), aqueous Na2CO3 (2M, 1 mL), ethanol (1 mL) and toluene (2 mL). The reaction was heated to 80° C. for 24 hours. The reaction mixture was dissolved into EtOAc and washed with brine. The organic layers were dried (MgSO4) and removal of the solvents in vacuo was followed by purification by flash column chromatography (SiO2) (30% EtOAc in hexanes) of the residue yielded the title compound (460 mg) as a brown oil. ESI-MS (m/z): Calcd. for C30H37N3O7S3: 648.2 (M+1) found: 647.9.
