Reaction Steps

A solution of 1-chloro-4-methoxyindan (from Step 3) in chloroform (130 ml) is added over a period of ten minutes to a stirred mixture of piperidine (284 ml) in chloroform (400 ml) under nitrogen. The reaction mixture is heated to reflux for six hours and allowed to stand at RT overnight. The mixture is treated with 10% aqueous HCl and the organic layer separated. The aqueous layer is extracted with methylene chloride and the combined organic extracts washed with 10% aqueous HCl. The organic layer is evaporated in vacuo and the residue partitioned between 5% aqueous HCl and ether. The combined aqueous fraction is washed with ether, made alkaline, and the alkaline layer extracted with ether. The ether extract is washed, dried and concentrated in vacuo yielding the piperidine indan as an oil.
