Versuchsvorschrift

To a stirring solution of #132 (1.33 g, 1.60 mmol, 1.0 eq) in 10 mL of THF diethylamine (5 mL, 50 mM, 31.3 eq) was added. The reaction was allowed to stir at room temperature for 4 hours. Reaction was concentrated in vacuo and the residue was purified by silica chromatography (Gradient: 0%-30% methanol in ethyl acetate) producing #133 (418 mg, 43%) as a white solid. LC-MS (Protocol Q1): m/z 605.2 [M+H+] retention time=1.48 minutes.
