70% aq. perchloric acid (4.34 g, 2.6 ml, 43.2 mmol, Eq: 4.12) was added to ethyl N-mesitylsulfonyloxyacetimidate (2.99 g, 10.5 mmol, Eq: 1.00) in THF (4 ml) at 0° C. The reaction mixture was stirred for 1 h at 0° C. The mixture was poured into water (60 ml) and extracted with CH2Cl2 (20 ml+2×10 ml). The combined organic layers were dried over Na2SO4. The solution was used without further purification in the next step.
