Reaction Steps

In a flame dried round-bottomed flask equipped with a magnetic stir bar and under inert atmosphere (N2), a solution of commercially available 6-oxo-heptanoic acid (2.00 g, 13.32 mmol) in THF (82 mL) at −30° C. was treated sequentially with Et3N (3.89 mL, 27.97 mmol) followed by isobutyl chloroformate (1.95 mL, 14.65 mmol). After stirring for 1 h at −30° C., serine methylester hydrochloride (2.32 g, 14.65 mmol was added and the reaction mixture was allowed to warm gradually to rt and stirred for an additional 2 h at rt. The resulting suspension was filtered, the solid washed with THF and the filtrate was concentrated under reduced pressure. Purification of the residue by FC (97:3 EA-MeOH) gave the title compound as a colorless oil. TLC: rf (97:3 EA-MeOH)=0.26. LC-MS-conditions 02: tR=0.56 min [M+H]+=246.44.
