I tried using diluted TFA and diluted HCl but the carbamate functional group is cleaving which should not happen in the acidic conditions.
Generally Boc is deprotected in acidic conditions, So If possible use Fmoc instead of Boc so that you can deprotect it in basic conditions.

You have to use some other fuctional group to have orthogonal deprotection
Thank you for ur answers but i can't change the carbamte and boc groups
You can try a microwave-aided inorganic base/MeOH combination, see Tetrahedron Letters 50 (2009) 1071–1074 and correspondig references cited therein. Besides, TMSBr or TMSCl/PhOH combination also works well, see Tetrahedron 61 (2005) 1595–1602.
It is difficult to say without knowing what other carbamates you have. I would suggest consulting Greene's "Protective Groups in Organic Synthesis".
If your molecule is stable enough, you can perform your Boc deprotection just with water @ 100°C. (DOI: 10.1039/B910239F)
Based on the stability of the molecule if you heat compound in the microwave at 150 °C , the boc group falls off.
