반응 단계

4.90 g (20.00 mmol) of potassium phosphate monohydrate were added under argon to a mixture of 4.16 g (10.00 mmol) of 5-(4-chlorophenyl)-2-(4-iodophenylethynyl)pyridine, 3.10 g (15.00 mmol) of tert-butyl (S)-2-aminomethylpyrrolidine-1-carboxylate, 194 mg (1.00 mmol) of CuI, 0.77 g (4.00 mmol) of N,N-diethylsalicylamide in 10 mL of DMF and the mixture was stirred for 16 hours at 100° C. The reaction mixture was combined with 100 mL of 5% aqueous ammonia, stirred, and the precipitate was filtered off. The precipitate was purified by MPLC (Hyperprep HS C18, 8 μm, gradient 0.15% formic acid in water/acetonitrile 10/90→90/10 v/v). 2 fractions were isolated. Fraction 1: yield: 0.48 g (10% of theoretical); C29H30ClN3O2 (M=488.020) molpeak (M+H)+: 488/490 (Cl); found: molpeak (M+H)+: 488/490 (Cl); Rf value: 0.60 (silica gel, PE/EtOAc 1:1).
