Is it possible to derive r=GM/c^2 classically(as in newtonian gravity) without using eeinstein field equation?

You can set the escape velocity to ##c## and find this radius immediately in Newtonian gravity: ##c=\sqrt{\frac{2GM}{r}}\rightarrow ~r=\frac{2GM}{c^2}## however, what this radius means in Newtonian gravity is not the same as what it means in GR.
