반응 단계

Methyl 5-chloro-2-(3-phenoxyazetidin-1-yl)nicotinate (D75) (305 mg, 0.96 mmol) was dissolved in methanol/tetrahydrofuran (10 ml/10 ml), 5N NaOH (10 ml) was added at 0° C. The resulting reaction mixture was heated to 35° C. for 18 hours then cooled to room temperature and concentrated. Water added (10 ml) and the mixture was acidified with 2.5N HCl (pH1-2). The white solid was collected, washed with water and dried to provide compound (D101) (280 mg) as a white solid.
