実験手順

Carbonyl diimidazole (95 mg, 0.58 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 (210 mg, 0.53 mmol) in DMF (2.0 ml). After 2 h at RT, concentrated aqueous ammonia (4.3 ml) is added, and the mixture is stirred for 15 minutes at RT. The emulsion is extracted with EtOAc. The organic layer is washed with brine and dried over Na2SO4. After concentration, the residue is purified by FCC (EtOAc) to yield the title compound. 1H NMR (d6-DMSO, 400 MHz): δ 1.38+1.46 (2x br s, 9H), 3.3-3.6 (br m, 2H), 4.08 (s, 2H), 4.40-4.65 (br m, 2H), 4.61 (s, 2H), 7.02 (br s, NH), 7.42 (br d, J=9 Hz, 1H), 7.48-7.58 (br m, 3H), 7.80-7.90 (br m, 2H), 7.95 (br d, J=9 Hz, 1H). ES+-MS: 412.3, 414.2 [M+H+H2O]+. ES−-MS: 393.3, 395.3 [M−H]−.
