Yield:6377-82-8 86%
Reaction Conditions:
with hydrogen bromide in diethyl ether at 60; for 0.166667 h;
Steps:
2.3. Preparation of morpholinium bromide; C4H10ONBr (2)
Morpholinium bromide was prepared by adding hydrobromicacid (2 mL) to morpholine (0.34 mL, 4 mM) in diethyl ether (6 mL)and then heated at 60 C for 10 min. On cooling, morpholiniumbromide precipitated out of the solution which was washed withdiethyl ether for three times. Yield: 86%, m. p.: 205-206 C.C4H10ONBr (168.03): cald.: C 28.59; H 6.00; N 8.34%; found: C28.56; H 5.96; N 8.30%. IR (KBr): n 3418, 3112, 2985, 2816, 2716,2515, 1634, 1562, 1451, 1305, 1186, 1099, 869, 594, 426 cm1. 1HNMR ([D6] DMSO, 400MHZ, ppm): d 3.765e3.790 (2.860) (t, 4H,2,6 -CH2), 3.081e3.104(3.669) (t, 4H, 3,5 -CH2), 9.017 (2H, br NH2).13C NMR ([D6] DMSO, 100MHZ, ppm): d 63.09 (68.16) (2,6- CH2),42.67 (46.61) (3,5-CH2).
