実験手順

A aqueous solution of NaOH (2 M, 0.59 ml, 1.17 mmol) was added at RT under an atmosphere of argon to a solution of (7-{[tert-butoxycarbonyl-(2-fluoro-ethyl)-amino]-methyl}-2-chloro-naphthalen-1-yl)-acetic acid ethyl ester (249 mg, 0.59 mmol) in dioxane (2.7 ml). The slightly turbid mixture is rendered clear by the addition of 6 drops of MeOH. After warming to 45° C. for 2.5 h, HPLC analysis indicated complete consumption of starting material. Removal of solvent yielded a residue, which was taken up in water. After acidification to pH 4 by the addition of 1 M HCl, the mixture was extracted with EtOAc. The organic layer was washed with brine, dried over Na2SO4 and concentrated. The crude product was used directly in the next step. ES+-MS: 413.3, 415.5 [M+H+H2O]+. ES−-MS: 394.2, 396.2 [M−H]−.
