Versuchsvorschrift
A solution of N-(3-isobutyrylpyridin-2-yl)pivalamide (3.10 g, 12.5 mmol), LDA (1.5 M, 17.50 mL, 2.1 eq) and t-butyl acetate (3.5 mL, 2.1 eq) were reacted as outlined in Scheme 1 to give tert-butyl 3-hydroxy-4-methyl-3-(2-pivalamidopyridin-3-yl)pentanoate which was used in the next step without further purification.
