실험 절차

A mixture of methyl (4-{4-bromo-3-cyano-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-2-thienyl}pyridin-2-yl)carbamate (1.14 g, 2.33 mmol), potassium vinyltrifluoroborate (0.624 g, 4.66 mmol), tetrakis(triphenylphosphine)platinum (0) (0.145 g, 0.116 mmol) and potassium carbonate (0.967 g, 7.00 mmol) in N,N-dimethylformamide (14.0 mL) and water (5.0 mL) in a microwave vial was heated under nitrogen atmosphere at 140° C. in a microwave for 15 min. The mixture was cooled to room temperature, quenched with water, extracted with DCM, washed with water then brine, dried over Na2SO4, filtered and rotavaped to give a crude product. Purification on a silica gel column using MeOH/DCM (0/100 to 5/95) afforded the desired product (1.16 g, with PPh3 and O═PPh3 contaminated) with Rf on TLC (MeOH/DCM 5/95) of 0.4, and de-carbamide product (0.627 g, yield 58%).
