実験手順

A solution of acid 7 (preparation described in scheme 2, example 1c, step 7) (140 mg, 0.303 mmol), methyl 2-(aminomethyl)benzoate hydrochloride (61.0 mg, 0.303 mmol), BOP (134 mg, 0.303 mmol) and triethylamine (0.127 mL, 0.908 mmol) in DMF (2 mL) was shaken for 16 hours at room temperature. It was then diluted with water (˜30 mL) and extracted into ethyl acetate (3×). The ethyl acetate was combined and washed with saturated NaHCO3, brine, dried over Na2SO4, filtered and concentrated. The crude was purified by silica gel chromatography using a 25S Biotage column with a gradient of 40-65% ethyl acetate in hexanes to give compound 15f (112.7 mg, 61.1% yield) as a white crusty solid. LRMS (ESI): calc. 609.2; found 632.1 (MNa)+
