I will present an analytic computation of the two-loop QCD corrections to ud->Wbb process for an on-shell W-boson using the leading colour and massless bottom quark approximations. The computation involves integration-by-parts reduction of the unpolarised squared matrix element using finite field reconstruction techniques and identifying an independent basis of special functions that allows an analytic subtraction of the infrared and ultraviolet poles.
