Phenylacetylene → HCID 54236800, compound

Participants

Reaction Steps

In place of phenylacetylene in Example 38 (2), 0.82 ml (6 mmol) of trimethylsilylacetylene was used to react with 880 mg (2 mmol) of 1-[(2-t-butyldimethylsilyloxyethoxy)methyl]-6-iodothymine for producing 1-[(2-hydroxyethoxy)methyl]-6-(2-trimethylsilylethynyl)thymine in the same manner as Example 38 (2). The obtained compound was dissolved in 100ml of methanol, was added to 1 ml of 1N sodium hydroxide aqueous solution and allowed to react for two minutes at room temperature. Then the reaction solution was neutralized with hydrochloric acid and concentrated. The resultant was distributed between ethyl acetate and aqueous layers, and the ethyl acetate layer then concentrated to dryness. The residue was crystallized from toluene/ethanol to obtain 170 mg of the target compound (Yield: 38%).
