Oxalic acid--2-oxa-6-azaspiro(3.3)heptane (1/1) → 5-tert-Butyl-3-(4-methoxy-benzyl)-7-(2-oxa-6-aza-spiro[3.3]hept-6-yl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine

Participants

Reaction Steps

In analogy to the procedure described for the synthesis of 4-(5-tert-butyl-3-(4-methoxy benzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidin-7-yl)morpholine (example 58, step c), the title compound was prepared from 5-tert-butyl-7-chloro-3-(4-methoxybenzyl)-3H-[1,2,3]triazolo[4,5-d]pyrimidine and 2-oxa-6-azaspiro[3.3]heptane oxalate and used without further purification in the consecutive step.
