반응 단계
A solution of L-methionine (274 mg, 1.84 mmol) in trifluoroacetic acid (5 mL) was added to a solution of benzyl (3R)-6-bromo-1-(2,4-dimethoxybenzyl)-2-oxo-2,3,4,7-tetrahydro-1H-azepin-3-ylcarbamate (90 mg, 0.184 mmol) in dichloromethane (5 mL). After 18 h, the mixture was concentrated. Purification by reverse phase HPLC (C-18, 95% water/acetonitrile→5% water/acetonitrile with 0.1% trifluoroacetic acid) gave the title compound (17 mg). MS 339 (M+1).
