with hydrogenchloride;water in 1,4-dioxane;Reflux;

Steps:

12 Preparation of 2-morpholino-2-phenylacetic acid hydrochloride (139).

Preparation of 2-morpholino-2-phenylacetic acid hydrochloride (139). Ethyl 2-moφholino-2-phenylacetate (0.34 g, 1.36 mmol) was dissolved in dioxane (1 1.4 ml) and 37% HCl (1.1 ml, 13.6 mmol) was added dropwise. The mixture was stirred at reflux overnight. 37% HCl (1.1 ml, 13.6 mmol) was added and the reaction was refluxed for additional 24 h. The solvent was evaporated and the residue was triturated with acetonitrile (10 ml) to obtain 2-moφholino-2-phenylacetic acid hydrochloride (0.22 g, 63.7 % yield) as a white solid. 1H NMR (300 MHz, DMSO-d6) ppm 1 1.79 (s, 1 H), 7.56 - 7.72 (m, 2 H), 7.37 - 7.56 (m, 3 H), 5.25 (s, 1 H), 3.60 - 4.10 (m, 4 H), 3.27 (br. s., 2 H), 2.96 (br. s., 2 H).
