Participants

Reaction Steps

To 65 ml. of allyl alcohol cooled to room temperature is added 2.8 g. of sodiuom followed by addition of an additional 120 ml. of allyl alcohol. To the resulting mixture at room temperature is added 15.0 g. of 5-chloro-8,9-dimethoxy-1,2,4-triazolo[4,3-c]quinazoline. The resulting precipitate is filtered off, washed with diethyl ether, dissolved in methylene chloride, washed with water, dried and evaporated in vacuo to dryness. The residue is twice crystallized from ethanol after treatment with charcoal to obtain 5-allyloxy-8,9-dimethoxy-1,2,4-triazolo[1,5-c]quinazoline, m.p. 189°-191° C.
