Participants

Reaction Steps

An alternative process consists in using titanium trichloride as reducing agent. Thus, in a reactor under nitrogen, protected from moisture and equipped with a magnetic stirrer, 5.0 g (10.7 minol) of the product of Example 20 are introduced into 42.8 ml of acetic acid. 64 mmol of TiCl3 (in 30% solution in 2N HCl) are added dropwise and the mixture is kept stirring for 30 min. It is then alcalinized with sodium hydroxide to a pH of 9, the medium being cooled by adding ice.
