Procedure

5.0 g of 1-methylpyrrolo[1,2-a]pyrazine prepared in Preparation Example 2 was dissolved in 60 ml of chloroform; and 6.7 g of N-bromosuccinimide was added thereto at 0° C. The reaction mixture was stirred for 30 minutes at the same temperature; and the resulting solution was concentrated. The residue was chromatographed over silica gel to obtain 6.3 g of title compound (yield: 80%).
