実験手順

Ethyl 4-methyl-3-{[3-(methyloxy)phenyl]methyl}pentanoate (66) (1.72 g, 6.51 mmol) was dissolved in THF (30 mL) and EtOH (30 mL). To this solution was added 1 N NaOH (35 mL). The reaction mixture was heated at 60° C. for 1.5 h. Cooled, the mixture was extracted with EtOAc. The combined extract was washed with brine, dried over Na2SO4, filtered, and the filtrate was concentrated to give 1.54 g (100%) of the crude product 67 as a yellow oil. The crude product was used without further purification. 1H NMR (400 MHz, CDCl3): δ 0.91 (d, J=6.9 Hz, 3H), 0.94 (d, J=6.7 Hz, 3H), 1.70-1.80 (m, 1H), 2.10-2.25 (m, 2H), 2.32 (dd, J1=15.3 Hz, J2=6.5 Hz, 1H), 2.46 (dd, J1=13.7 Hz, J2=8.2 Hz, 1H), 2.67 (dd, J1=13.7 Hz, J2=6.4 Hz, 1H), 3.79 (s, 3H), 6.70-6.80 (m, 3H), 7.15-7.25 (m, 1H).
