| titleOfInvention | PROCESS FOR THE PREPARATION OF 4-AMINO-MORPHOLINE |
| abstract | Prepn. of 4-aminomorpholine (I) comprises reacting morpholine-4-carboxamide (II) with alkali hypochlorite (III) in aq. soln. in the presence of alkali hydroxide (IV). Pref. the aq. reactants are mixed at 0-10 degrees C then the mixt. is allowed to warm to 20-25 degrees C. Pref. mole ratios are (IV):(II) 2-4 (3):1 and (III):(II) 1.5-1(1.3):1. (I) is an intermediate for organic cpds. esp. pharmaceuticals. Excellent yields (about 84% and product purity are achieved in a simple process. In an example aq. solns of (II), NaOH (4 moles) and 11% NACL (1.3 moles) were mixed at 0 degrees C, reacted at 25 degrees C then benzaldehyde added. The benzylidene deriv. formed was hydrolysed with aq. acid to give 83.1% of (I). |
