Reaction Steps
1.0 g of pyrrolo[1,2-a]pyrazine prepared in Preparation Example 1 was dissolved in 10 ml of tetrahydrofuran and then cooled to -78° C. under nitrogen atmosphere. To this solution was added 1.2 equivalents of LDA solution; the resulting mixture was stirred for 30 minutes; and 1 ml of iodoethane was added to the mixture while maintaining the temperature of -78° C. The reaction mixture was stirred for 30 minutes, warmed to room temperature and then poured into water. The organic layer was isolated and then concentrated to dryness to obtain 0.3 g of title compound.
