$$ \rho_L(x) = \frac{-1}{2\pi} \partial_x \phi_L^{(G))} = \frac{-1}{2\pi} \partial_x \phi_L $$
From the commutation relation of Giamarchi (2.25) $[ \phi(x), \partial_y \theta (y) ] = i \pi \delta(x-y)$ we can backtrack the commutation relations of the chiral fields after we substitute the field redefinition into the above commutator:
$$ \phi =
\frac{\phi_R^{(G)} \frac{\phi_L^{(G)} -
\phi_L^{(G)}}{2} \phi_R^{(G)}}{2} $$
$$ \theta = \frac{\phi_L^{(G)} + \phi_R^{(G)}}{2K} $$
$$ \frac{1}{4K} \left[ \phi_L^{(G)}, \partial_x \phi_L^{(G)} \right] + \frac{1}{4K} \left[ -\phi_R^{(G)}, \partial_x \phi_R^{(G)} \right] = i \pi \delta(x-y) $$
