A mixture of N—((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-methoxybenzamide (3.0 g), glacial acetic acid (2 ml) and HBr (20 ml; 48% in water) was heated in a closed glass vessel in a microwave reactor to 150° C. for 25 minutes. The precipitate obtained after cooling was filtered off. The product was thus obtained with the molecular weight of 346.23 (C17H16BrNO2); MS (ESI): 346 (M+H+). Both N—((S)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-methoxybenzamide and N—((R)-6-bromo-1,2,3,4-tetrahydronaphthalen-2-yl)-4-methoxybenzamide can be obtained by literature methods (J. Org. Chem. 1995, 60, 4324).
