実験手順
To a solution of trans-4-hydroxycyclohexanecarboxylic acid (14.7 mmol, 2.12 g), K2CO3 (17.6 mmol, 2.44 g) in DMF (15 mL) is added iodomethane (17.6 mmol, 1.10 mL). After stirring for 2 hours, the mixture is diluted with EtOAc. The mixture is washed with H2O and brine, dried over Na2SO4 and concentrated. The obtained residue is used to next reaction without further purification (1.62 g, 70%); 1H-NMR (400 MHz, CDCl3): 1.24-1.33 (m, 2H), 1.45-1.53 (m, 2H), 1.98-2.28 (m, 4H), 2.21-2.29 (m, 1H), 3.57-3.64 (m, 1H), 3.67 (s, 3H).
