Versuchsvorschrift

Methyl 2-(hydroxymethyl)isonicotinate (3.17 mmol, 0.530 g) and triethylamine (9.51 mmol, 1.322 mL, 0.963 g) were stirred in dichloromethane (20 mL) at 0° C. Methanesulfonyl chloride (4.76 mmol, 0.368 mL, 0.545 g) was added dropwise and the reaction stirred at room temperature for 1 hour. The reaction mixture was washed with water, dried over sodium sulfate and concentrated under vacuum to afford the title compound (686 mg). MS (ESI) m/z 246.4 [M+H]+
