Versuchsvorschrift
Iodide 68 (311 mg, 1.00 mmol) was coupled to N-propargyltrifluoroacetamide (43) according to the general procedure described in EXAMPLE 1C. Flash chromatography on silica gel (3×20 cm) with 5%, 10% and 20% methanol in dichlormethane afforded alkynylamino nucleotide 69 as a pale yellow foam (77.4 mg, 23%).
