実験手順

To a solution of 6-amino-5-iodonicotinic acid (330 mg, 1.3 mmol), N,N-diisopropylethylamine (0.44 mL, 2.5 mmol), and (S)-(+)-S-methyl-S-phenylsulfoximine (291 mg, 1.9 mmol) in 7.0 mL DMF at room temperature was added BOP (608 mg, 1.4 mmol). The solution was stirred 10 minutes and then heated at 60° C. for 5 hours. The mixture was dissolved in EtOAc, washed with Na2CO3 solution, H2O, brine, dried with anhydrous Na2SO4 and rotary evaporated. The brown oil was purified by chromatography (silica gel, hexane/acetone). The product containing fractions were purified by chromatography one additional time (silica gel, EtOAc/MeOH). To give the title compound as a white foam (354 mg, 71%).
