실험 절차

2,4-Bis(4-methoxyphenyl)-2,4-dithioxo-1,3,2,4-dithiadiphosphetane (1.6 g, 0.0038 mol) was added to a solution of tert-butyl [(1R)-2-amino-1-methyl-2-oxoethyl]carbamate (1.45 g, 0.00770 mol) in 1,2-dimethoxyethane (40 mL). The resulting suspension was stirred at RT for 5 h. After removal of solvent the residue was taken up into ethyl acetate. It was washed with 0.1 N NaOH solution, water, brine; dried over Na2SO4. After filtration the filtrate was concentrated to yield 1.58 g of the product. (yield: ˜100%).
