Reaction Steps
0.53 g(1.69 mmol) of methyl α-(2-dimethylaminoethoxy)-α-phenyl-p-toluate) was dissolved in 10 ml of methanol. 2.54 ml of a 1N sodium hydroxide aqueous solution was added thereto and the mixture was refluxed under heating for 1 hour. After the reaction mixture was cooled, 2.54 ml of IN hydrochloric acid was added thereto and the mixture was concentrated to dryness. A mixture of chloroform and methanol (5:1 (v/v)) was added to the residue, and the resulting mixture was stirred for a while, then filtered with Celite. The solvent was distilled off and the residue was triturated with diethyl ether. The resulting precipitate was collected by filtration to obtain 0.44 g (1.47 mmol) of α-(2-dimethylaminoethoxy)-α-phenyl-p-toluic acid as pale yellow brown powder. ##STR11## Its spectroscopic data are as follows: 1H-NMR (CDCl1) δ (ppm) 2.62 (6H, s), 3.00 (2H, m), 3.59 (1H, m), 3.82 (1H, m), 5.37 (1H, s), 7.21~7.36 (7H, m), 7.77 (2H, d, J=8.4 Hz).
