A mixture of 1,1-dimethylethyl 2-methyl-2-(4-oxo-1-piperidinyl)propanoate (Int. A6) (370 mg, 1.2 equiv), {[4′-(trifluoromethyl)-4-biphenylyl]methyl}amine (Int. A1) (397 mg, 1 equiv), sodium triacetoxyborohydride (400 mg, 1.5 equiv), DCM (10 ml) and acetic acid (0.076 ml, 1 equiv) was combined and stirred at room temperature until LCMS confirmed disappearance of the amine starting material (approx. 18 hours). Aqueous sodium carbonate was added and then extracted with DCM. The organics were dried over sodium sulfate and concentrated to give a solid (420 mg) that was used without further purification.
