Participants

Reaction Steps

A suspension of the compound obtained in Step E of Example 1 (1.26 g, 3.0 mmol) in 18 ml of 28% ammonium hydroxide solution is stirred. After a few minutes the batch is observed to pass into solution. Stirring is maintained for 30 minutes and the reaction mixture is rendered acidic with 4N HCl. A few ml of ethyl acetate are added with stirring and precipitation occurs. The precipitate is filtered off and dried in vacuo to yield the title product in the form of a cream-coloured powder.
