Procedure

To a solution of tert-butyl[(3S,5S,6R)-6-methyl-5-phenyl-2-thioxopiperidin-3-yl]carbamate (150 mg, 0.47 mmol) in ethanol (4.7 mL) was added 1-amino-3-methoxy-3-methylbutan-2-ol (156 mg, 1.17 mmol), mercury (II) chloride (165 mg, 0.61 mmol), and triethylamine (163 μL, 1.17 mmol). The mixture was stirred 20 min, and then concentrated, giving the crude title compound. MS 420.4 (M+1).
