Ammonia → HCID 69025297, compound

Participants

Reaction Steps

Triethylamine (9.4 μL, 0.067 mmol) and ethyl chloroformate (3.1 μL, 0.032 mmol) were added sequentially to a solution of {4-[(R)-2-((E)-3-hydroxy-4-phenyl-but-1-enyl)-6-oxo-piperidin-1-yl]-but-2-ynyloxy}-acetic acid (11.8 mg, 0.032 mmol) in CH2Cl2 (0.2 mL) at 0° C. After 1 h at 0° C., ammonia (0.5 M in 1,4-dioxane, 0.32 mL, 0.16 mmol) was added and the reaction mixture was allowed to warm to rt. After 17 h at rt, the reaction mixture was treated with saturated aqueous NaHCO3 (10 mL) and extracted with CH2Cl2 (3×10 mL). The combined extracts were dried (Na2SO4), filtered and concentrated in vacuo to afford 11 mg (93%) of the title compound.
