(trans)-N-[[(2-Propen-1-yloxyphenyl)cyclopropyl]methyl]butanamide: To a rapidly stirred solution of (trans)-N-[[2-(3 hydroxyphenyl)cyclopropyl]methyl]butanamide (0.8 g, 3.4 mmol) and KOH (210 mg, 3.74 mmol) in ethanol (15 mL) was added allyl iodide (622 mg, 3.7 mmol). After stirring for 18 h, the suspension was diluted with Et2O (100 mL), and washed with H2O, 2N NaOH, brine, dried (K2CO3), and concentrated to a give a crude residue. The resulting material was purified by chromatography (silica gel, 40% EtOAc/hexane) to afford 320 mg (34%) of the title compound: 1H NMR (300 MHz, CDCl3) δ 0.70-0.94 (m, 5H), 1.12-1.32 (m, 1H), 1.58-1.84 (m, 3H), 2.20 (t, J=6.0 Hz, 2H), 3.15-3.36 (m, 2H), 4.48 (d, J=5.6 Hz, 2H), 5.24 (d, J=10.0 Hz, 1H), 5.40 (d, J=17.2 Hz, 1H), 5.56 (br s, 1H), 5.96-6.07 (m, 1H), 6.57-6.70 (m, 3H), 7.13 (t, J=7.2 Hz, 1H); IR (NaCl Film) 3296, 2962, 1644, 1607, 1548, 1494 cm-1 ; MS m/e 273; Analysis calc'd for C17H23NO2 0.20(H2O): C, 73.72; H, 8.52; N, 5.06; found: C, 73.77; H, 8.63; N, 5.00.
