90% | A suspension of [2-(tert-butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid ethyl ester (12.3 g, 42.7 mmol) and LiOH (8.9 g, 214 mmol) in H2O (20 mL) and THF (100 mL) was stirred overnight. Volatile solvent was removed under vacuum and the residue was extracted with ether (2×100 mL). The aqueous phase was acidified to pH 3 with dilute HCl solution, and then extracted with CH2Cl2 (2×300 mL). The combined organic layers were washed with brine, dried over Na2SO4 and concentrated under vacuum to give [2-(tert-butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid as a colorless oil (10 g, 90%). 1H NMR (CDCl3) δ 7.17 (br s, 1H), 4.14-4.04 (m, 4H), 3.04-2.88 (m, 6H), 1.45-1.41 (m, 9H); ESI-MS 282.9 m/z (M+Na+). | |
To (ter^-butoxycarbonyl-methyl-amino)-acetic acid (2.73 g, 14.4 mmol) in 70 mLof THF was added sequentially diisopropyl ethylamine (7.5 mL, 14.4 mmol) and HBTU (5.47 g,14.4 mmol), and the reaction mixture was stirred at room temperature for one hour. To thisreaction mixture was added methylamino-acetic acid ethyl ester (2.22 g, 14.4 mmol) in oneportion, and the reaction mixture was heated at 65 C for 12 h. The reaction mixture was cooled,diluted with a solution of saturated NaHCC>3, and extracted with EtOAc. The organic layer wasseparated and dried over Na2SC>4, and the solvent was removed under reduced pressure to -(ter^-butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid ethyl ester.The ester was taken up in 49 mL of methanol, and to this was added a 1 M NaOHsolution (25.1 mL, 25 mmol). The reaction mixture was heated at 65 C for 3 h. The reactionmixture was cooled, and methanol was removed under reduced pressure. The residue wasdiluted with 50 mL of water and acidified with glacial acetic acid until the pH was 5. Thissolution was extracted with EtOAc (50 mL), and the organic layer was separated and dried overNa2S04, and the solvent was removed under reduced pressure to give [2-(fert-Butoxycarbonyl-methyl-amino)-acetyl]-methyl-amino}-acetic acid as an oil. |
