Abstract
Method for the preparation of a compound of formula ** (See formula) ** wherein Ph is phenyl and n is a whole number consisting of 1, 2 and 3, comprising the reaction of a molecular ratio of at least liquid ammonia in an ether medium, with a molecular proportion of a compound of formula ** (See formula) ** at about room temperature, to form an intermediate product of formula ** (See formula) ** which is refluxed with an equivalent amount of an alkali metal hypobromite in methanol to form a second intermediate of formula ** (See formula) ** this second intermediate product is then refluxed with an alkali metal hydroxide in aqueous methanol and the resulting product separated from the reaction mixture.
