EDC (1.1 eq.) was added in small portions over 1.5 h to a stirred mixture of hept-6-enoic acid, methoxy(methyl)ammonium chloride (1.1 eq.) and DMAP (1.1 eq.) in CH2Cl2 (0.2 M). After 14 h, the mixture was diluted with CH2Cl2, then washed sequentially with hydrochloric acid (1 M), NaOH (1M), brine and dried (Na2SO4). Evaporation of the solvent afforded the title compound (97%) as a colorless oil. 1H NMR (400 MHz, CDCl3, 300 K) δ 5.87-5.75 (m, 1H), 5.01 (d, J 17.1, 1H), 4.95 (d, J 10.1, 1H), 3.68 (s, 3H), 3.18 (s, 3H), 2.48-2.36 (m, 2H), 2.13-2.04 (m, 2H), 1.71-1.60 (m, 2H), 1.50-1.40 (m, 2H).
