1-piperidinyl cyclohexanecarbonitrile

When making alpha-amino nitriles, how can the best yields be obtained? A friend told me that it's a bad thing if there's excess NaOH left over in a homemade NaCN solution. Before adding the amine and cyclohexanone, what could be added to neutralize the NaOH that wouldn't fuck with the sodium cyanide. If someone's shit-out of litmus strips, then are they fucked?
