Procedure

Crude (R)-3-((R)-(3-methoxypropoxy)(phenyl)methyl)piperidine-1-carbonyl chloride (60 mg, 0.184 mmol), 2-(trimethylsilyl)ethyl (S)-2-amino-3-cyclohexylpropylcarbamate (69 mg, 0.23 mmol, 1.25 equiv) and triethylamine (64 μL, 0.46 mmol, 2.5 equiv) were combined in CH2Cl2 (1 mL) at rt and left on the shaker overnight. After concentration, the product was isolated by prep HPLC to afford 2-(trimethylsilyl)ethyl (S)-2-((R)-3-((R)-(3-methoxypropoxy)-(phenyl)methyl)piperidine-1-carboxamido)-3-cyclohexyl-propylcarbamate (85.3 mg, 79%). LC-MS (3 min) tR=2.44 min, m/z 590 (M+1).
