Participants

Reaction Steps

To a solution of the compound (1.087 g), which had been obtained in (1), in anhydrous dichloromethane (5 ml), trifluoroacetic acid (2 ml) was added dropwise under ice cooling. The resulting mixture was treated in a similar manner to that described in Referential Example 16-(2), whereby the title compound was obtained. The product was provided for use in the subsequent reaction without isolation, Infrared absorption spectrum (KBr) νmax cm-1 : 3290, 1739, 1674, 1645, 1625, 1555, 1524.
