4-(3,4-Dichlorophenoxy)-1,4′-bipiperidine (2.0 g) was dissolved in glacial acetic acid (0.608 ml), the solution was diluted with water (6 ml) and added with stirring to a solution of sodium cyanate (0.395 g) in warm water (3 ml). The reaction was allowed to stand for 30 mins. 2M Sodium hydroxide solution was added until the solution was alkaline. The resulting precipitate was collected and washed with water followed by dichloromethane and then dried to leave the sub-title compound (1.3 g; ES+ 372/374).
