Procedure

A mixture of N—((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-hydroxybenzamide (5.00 g), bromomethylcyclopropane (2.20 g), cesium carbonate (5.5 g) and DMF (50 ml) was heated to 75° C. for 12 hours. The cooled reaction mixture was admixed with water and extracted with ethyl acetate. The organic phase was washed three times with water, dried over magnesium sulfate and concentrated. The product was thus obtained with the molecular weight of 400.32 (C21H22BrNO2); MS (ESI): 400 (M+H+).
