Participants

Reaction Steps

Combine a mixture of 7-amino-6-oxo-heptanoic acid methyl ester and 5-amino-6-oxo-heptanoic acid methyl ester hydrochlorides (2.36 g, 11.3 mmol) with o-anisic acid (1.71 g, 11.3 mmol), 1-(dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (2.16 g, 11.3 mmol), 1-hydroxybenzotriazole hydrate (11.3 mmol), N,N-diisopropylethylamine (5.88 mL, 33.8 mmol) in DMF and stir for 24-48 hours. Dilute the mixture with water and extract with EtOAc. Wash the combined extracts with brine and dry over Na2SO4 before concentrating. Chromatograph the residue over silica gel (MeOH/CH2Cl2) to allow for isolation of a mixture of 7-(2-methoxy-benzoylamino)-6-oxo-heptanoic acid methyl ester and 5-(2-methoxy-benzoylamino)-6-oxo-heptanoic acid methyl ester (3.45 g, 99%). MS (ES): (M+1)+ 308.1 m/z.
