According to some reports, Vulpea was one of the three "Caimacami" (regents) upon Soutzos' death. His brother Grigore, also credited as a "Caimacam", was himself involved in the Russian conspiracy during those months. He was unreliable from Pini's perspective, and looked to Austria for additional guidance. As the Eterists and the National Party colluded in the build-up to the Greek Revolution, the Filipescus withdrew from the intrigues. In June 1820, by his own admission, Dimitrie Macedonski wanted to co-opt Alecu into a rebellion against Soutzos and the Phanariotes. Filipescu agreed on principle that "it would be possible and rather good that we remove this country of ours from the yoke of [Phanariote] tyrants"; still, he adamantly refused to be involved beyond this statement, feeling himself betrayed by the National Party. However, with Pini's assurances and possibly seeking appointment in a revolutionary government, he abetted the Eterists, without formally rejoining their movement.
