実験手順

N-(1-(7-Benzyl-1,3-dimethyl-2,6-dioxo-1,2,3,6-tetrahydropurin-8-yl)azepan-3-yl)-4-methylbenzenesulfonamide (6C) (100 mg, 0.19 mmol) was dissolved in hydrobromic acid (48%, 5 ml) and benzene (0.07 ml), and phenol (61.4 mg, 0.65 mmol) was added. The mixture was heated to reflux for three hours, and after cooling 20 ml of EtOAc was added. The layers were separated, and the aqueous layer washed with 20 ml of EtOAc. pH was adjusted to 11 with 10M sodium hydroxide. The aqueous layer was extracted with diethyl ether (3×20 ml), and the combined organic layers were dried over sodium sulphate and the solvent was evaporated. The crude product was dissolved in 5 ml of DCM and 0.5 ml of trifluoroacetic acid was added. The solvents were evaporated and the crude product was purified by preparative HPLC (method A1, Rt=7.63 min). Evaporation of the solvent gave the title compound as an oil.
