실험 절차
15 g of 3-pentyn-1-ol was reacted with 8.35 g of maleic anhydride in 25 ml of toluene and in the presence of one drop of methanesulfonic acid. 11.5 g of DPTNM was isolated from the reaction mixture (bp=134-140° C./full vacuum GC purity=98.8%). 1H NMR data: 1.77(t, J=3 Hz, CH3), 2.52 (m, CH2CC), 4.22(t, J=7 Hz, CH2 --O), 6.22(s, maleate olefin CHs).
