Reaction Steps

A 100 ml 3-necked flask equipped with a condenser, addition funnel and magnetic stirring bar and under a nitrogen atmosphere was charged with a solution of homopiperazine (3.0 g; 30.5 mmol) in DMAC (35 ml). Potassium iodide (300 mg) was added followed by the addition of a solution of 4-chloro-3,4-dihydro-2H-benzothiopyran (1.15 g; 6.1 mmol) in DMAC (15 ml). This solution was then heated in an oil bath at 60° C. overnight. The reaction mixture was partitioned between water and ethyl acetate, washed with brine and dried with magnesium sulphate. Filtration and evaporation of solvent gave a yellow oil (1.15 g) which exhibited a satisfactory proton nmr spectrum (300 MHz, CDCl3). This material was used without further purification.
