2-Isopropyl-3,6-dimethoxy-5-[2-(2,2,2-trifluoro-ethoxy)-ethyl]-2,5-dihydropyrazine → 2-Methoxycarbonylamino-4-(2,2,2-trifluoro-ethoxy)-butyric acid methyl ester

Participants

Reaction Steps

This compound was made by the same procedure as 5,5,5-Trifluoro-2-methoxycarbonylamino-pentanoic acid methyl ester, using 2-Isopropyl-3,6-dimethoxy-5-[2-(2,2,2-trifluoro-ethoxy)-ethyl]-2,5-dihydropyrazine as the starting material. 1H-NMR: 400 MHz, (CDCl3) δ: 5.51-5.43 (br, 1H), 4.51-4.43 (m, 1H), 3.83-3.63 (m, 10H), 2.22-2.13 (m, 1H), 2.13-2.03 (m, 1H) ppm.
