Versuchsvorschrift

A solution of methyl magnesium bromide (1M in THF) (3.03 mL, 3.03 mmol) was added drop wise to a solution of methyl 6-formylpyridine-3-carboxylate (Intermediate 195, 0.50 g, 3.03 mmol) in THF (20 mL) at −78 C. The reaction mixture was stirred at −78 C for 1 h and water (20 mL) was added. The mixture was warmed to room temperature and extracted with EtOAc (3×20 mL). The organic extracts were combined, dried over sodium sulfate, filtered and concentrated under vacuum to provide the title compound as an off-white solid (0.407 g, 74%). Method B HPLC-MS: MH+ requires m/z=182 Found: m/z=182, Rt=1.11 min (98%).
