Reaktionsschritte

At 0° C. and under argon, 393 mg (2.394 mmol) of 4-formyl-N-methylpyridine-2-carboxamide Example 42A were initially charged in 66 ml abs. tetrahydrofuran. At 0° C., 343 mg (2.873 mmol) of methylmagnesium bromide [1.4 mol in toluene/tetrahydrofuran 3/1] were added dropwise, and the reaction solution was stirred at this temperature for 1 h. 200 μl of semisaturated aqueous sodium bicarbonate solution and 200 ml of ethyl acetate were added to the reaction solution. The precipitate was filtered off and washed with ethyl acetate. The filtrate was evaporated.
