Procedure

[(3R,4S)-4-Amino-1,1-dioxo-tetrahydrothiophen-3-yl]-[(S)-3-(4-fluorobenzyl)-piperidin-1-yl]-methanone (50 mg, 141 μmol) and [5-acetyl-4-methylthiazol-2-yl]-carbamic acid phenyl ester (43 mg, 155 μmol) were dissolved in N,N-dimethylformamide (1 mL) and treated with triethylamine (22 μL, 155 μmol). The mixture was stirred at room temperature for 94 h, and then concentrated. The residue was purified by flash column chromatography (4% methanol/dichloromethane containing 0.4% aqueous ammonium hydroxide) to provide a white solid (41 mg, 55%).
