We have searched for the decay B⃗D_(s1)^+(2536)X and measured an upper limit for the inclusive branching fraction of B(B⃗D_(s1)^+X)<0.96% at the 90% confidence level. This limit is small compared with the total expected B⃗D^((*))D^((*))KX rate. Assuming factorization, the D_(s1)^+ decay constant is constrained to be fD_(s1)^+<114 MeV at the 90% confidence level, at least 2.5 times smaller than that of D_s^+.
