How Basic is NaSH Compared to NaOH in Organic Synthesis?

[gravenewworld]

I am using NaSH to make a mercaptan by refluxing a bromo pyridine in ethanol. The only thing is that my pyridine also has an amide moiety, and I am afraid of the basicity of NaSH (since S is 1 below O on the periodic table). If I reflux this reaction I am afraid I might hydrolyze off the amide, so I was wondering, how basic is NaSH compared to NaOH?

Hi

I think it is less basic than NaOH, since the acidic adduct of NaSH is H₂S, where NaOH produces H₂O. Since the former product is more acidic, the parent compound (NaSH) must be less basic.
