  • Reaction of 6-(acetoxymethyl) -2,4-dichloropyrido [3,2-d] pyrimidine (I) with some nucleophiles was investigated. When I reacted with sodium azide afforded 2,4-diazido derivative (II). Treatment of II with sodium hydroxide underwent cyclization of the 2-azido group to tetrazolo, replacement of 4-azido group by hydroxide ion, and hydrolysis of 6-ace-foxy moiety to hydroxy methyl derivative (III). While, reaction of I with hydrazine hydrate resulted in the formation of 2,4 dihydrozino-6-hydroxymethyl derivative (lV).
