97% | In ethanol; at 50℃; for 4h; | To the solution of CEE hydrochloride 22 (1 .0 mmol, 195 mg) in EtCH (15 mL)equimolar quantity of sweetener salt (potassium 6-methyl-4-oxo-4H-1 ,2,3-oxathiazin-3-ide2,2-dioxide 0.201 g for 20a and sodium benzo[d]isothiazol-3-olate 1,1-dioxide hydrate 0.205g for 20b) was added and the mixture was then stirred for 4h at the 50 C. Sodium or potassium chloride, formed during the reaction, was separated by filtration through the 22 micron membrane filter and the filtrate was taken to dryness. Diethyl ether was added to the products and after it was evaporated, products 23a and 23b were isolated as white solids in quantitative yields.White solid (97%, 0.312 g, 0.97 mmol). M.p. 118.9- 122.0 C; 1H NMR (500 MHz, CD3OD, 5)5.56(s, 1H), 4.30-4.24 (m, 4H), 3.11 (5, 3H), 2.09 (5, 3H), 1.33 (t, J= 7.2 Hz, 3H); 13C NMR (125 MHz, CD3OD, 5)173.2, 169.8, 164.4, 160.0, 102.7, 63.4, 53.1, 38.4,20.3, 14.9. HRMS (ESI) calcd for C6H14N302 [M+H] 160.1081, found 160.1079; HRMS (ESI) calcd for C4H4N045 [M-H]- 161 .9867, found 161 .9868. |
