Reaction Steps

A solution of Kryptofix (Fluka, 15 mg, 40 μmol) in dry acetonitrile (200 μl) was added to solid potassium fluoride (2.3 mg, 80 μmol). The mixture was shaken for 5 min. The Kryptofix/KF-solution was added to a solution of methanesulphonic acid 4-[2-(tritylsulphanyl)ethylcarbamoyl]benzyl ester (21 mg, 40 μmol) in acetonitrile (400 μl). The mixture was heated at 65° C. for 10 min. An aliquot was analysed by HPLC (column Phenomenex Luna 3 μm C18(2) 50×4.60 mm; solvents: A=water/0.1% TFA and B=acetonitrile/0.1% TWA; gradient 40-80% B over 10 min; flow 2.0 ml/min, UV detection at 214 and 254 nm), showing complete conversion of starting material (tR 5.6 min) to a new product (tR 6.3 min). Purification by reverse phase preparative HPLC (column: Phenomenex Luna C18(2) 5 μm 250×21.2 mm, solvents: A=water/0.1% TFA and B=acetonitrile/0.1% TFA; gradient 40-80% B over 60 min; flow 10.0 ml/min, UV detection at 214 nm) gave 4.5 mg of white solid. The structure was confirmed by NMR spectroscopy.
