I don't find any process to synthetize piperonal from 3-4 dihydroxybenzaldehyde. Is it possible to do like the first step of this synth with benzaldehyde insteed benzene?

3,4-dihydroxybenzaldehyde is also known as protocatechualdehyde.
Methylenation reactions can be found in https://www.rhodium.ws/chemistry/methyle

Thanks !
But now the problem is that I don't own an autoclave. Is it possible to replace CH2Cl2 by CH2BR2(b.p. 97°)and reflux the whole instead heat under presure?

Yes, dibromomethane or diiodomethane may be used instead. In the link I posted there are a PTC reaction which does not use an autoclave too.
