Reaction Steps
Analogously to the description in Example 11, 8.2 g (0.05 mol) of 2,3-dichloro-5-methyl-pyrazine, 11 g (0.05 mol) of 2-phenyl-3-isopropyl-5-hydroxymethyl-oxazolidine and 3.4 g of a 50% strength suspension of sodium hydride in paraffin oil give 2-chloro-3-(3'-isopropylamino-2'-hydroxy-propoxy)-5-methyl-pyrazine, melting point 109°-110° C. when crystallised from benzene. The fumarate prepared therefrom by means of fumaric acid crystallises from methanol-ether, melting point 164°-165° C.
