trans-2-Decenoic acid → HCID 117920261, compound

Participants

Reaction Steps

The same procedures as in Example 2 were carried out using (E)-2-decenoic acid and ethyl 3-piperazin-1-yl propionate dihydrochloride (ethyl ester of Compound 21) as starting raw materials, to produce ethyl 3-[4-((E)-2-decenoyl)piperazin-1-yl]propionate, and subjected to alkali saponification, to obtain an intended compound as white crystals. White crystals, mp 53°-55° C., C17H30N2O3 MW 310.4, EIMS: m/z 311 [M+H]+, 1H-NMR (500 MHz, DMSO-d6) δ: 0.86 (t, J=7.0 Hz, 3H), 1.19-1.31 (m, 8H), 1.35-1.44 (m, 2H), 2.12-2.20 (m, 2H), 2.32-2.43 (m, 6H), 2.55-2.61 (m, 2H), 3.43-3.57 (m, 4H), 6.45 (d, J=15.0 Hz, 1H), 6.65 (dt, J=15.0, 7.0 Hz, 1H), 11.70-12.70 (brs, 1H).
