| titleOfInvention | 2-Amino-3-chloromethyl-5-(dichloromethyl)-pyrazines and process for their preparation |
| abstract | 2-Amino-3,5-di (halomethyl) pyrazines of the general formula I in which X represents either chlorine or bromine, m and n can each represent the numbers 0, 1, 2 or 3 and R 1 and R 2 represent hydrogen or a protective group, where R 1 and R 2 can also be linked to one another.n n n The compounds of the formula, in particular those in which m is 1 and n are 2 and / or R 1 and R 2 together are a phthaloyl radical, are valuable intermediates for the pteridine component of folic acid or folic acid analogs. They are obtained in that man 2-amino-3,5-dimethyl-pyrazine of the general formula II treated with a chlorinating or brominating agent and, if R 1 and / or R 2 are protective groups, if desired these are split off again after the chlorination or bromination has ended. |
