Boc-L-methionine → HCID 69492394, compound

Participants

Reaction Steps

Condensation of (S)-BOC-methionine and 4-(3-fluorobenzyloxy)-phenylamine [Example 3b)] by HBTU yields the (S)-{1-[4-(3-fluoro-benzyloxy)-phenylcarbamoyl]-3-methylsulfanyl-propyl}-carbamic acid tert-butyl ester as a light yellow solid; MS: m/e=449 (M+H)+. The following methylation and cyclisation yields the (S)-{1-[4-(3-fluoro-benzyloxy)-phenyl]-2-oxo-pyrrolidin-3-yl}-carbamic acid tert-butyl ester as a white solid; MS: m/e=401 (M+H)+. The cleavage of the BOC-group yields the (S)-3-amino-1-[4-(3-fluoro-benzyloxy)-phenyl]-pyrrolidin-2-one hydrochloride as a white solid; MS: m/e=301 (M+H)+.
