Hi, I am new to Mathematica. I want to solve a simple equation with a domain restriction but I don't understand how to specify the domain.

Example:
Find all solutions of
2*Sin[x]+1==0
such that 0 < x < 2*Pi

I tried
Solve[2*Sin[x]+1==0, x, 0<x<2*Pi]
but mathematica complains:
"0<x<2*Pi is not a valid domain specification"
