실험 절차

To a solution of 5-(1-methyl-1H-pyrazol-5-yl)-3-thiophenecarboxylic acid (104 mg, 0.5 mmol), PyBrOP (384 mg, 0.83 mmol) and diisopropylethyl amine (0.14 mL, 0.83 mmol) in DCM (8 mL) at 25° C. was added 1,1-dimethylethyl [2-amino-2-(1-naphthalenyl)ethyl]carbamate (144 mg, 0.5 mmol) [from Preparation 6]. After 16 h, the solution was partitioned between H2O and washed with DCM. The combined organic fractions were dried (Na2SO4), concentrated and purified via column chromatography (silica) affording the title compound (76 mg, 32%) as a white solid: LC-MS (ES) m/z=477 (M+H)+.
