実験手順

To 156AF03-217 (552 mg, 2 mmol) in THF (20 mL) under argon atmosphere at −78° C. was added dropwise lithium bis(trimethylsilyl)amide (2.6 mL, 2.6 mmol, 1 M in THF). After 30 min at −78° C., iodomethane (2.0 mL) was added over 1 min and the reaction was allowed to warm to rt overnight. Partitioning of the reaction mixture between ethyl acetate (2×500 mL) and water (500 mL), drying of the combined organic phases over Na2SO4, filtration, removing of volatiles in vacuo and purification by preparative TLC (ethyl acetate/n-heptane 1:4, 5× eluted) afforded the title compound (115 mg, 20%) as a thick oil.
