実験手順

To a solution of tert-butyl N-(2-[4-hydroxythieno[2,3-d]pyrimidin-6-yl]ethyl)carbamate (2.3 g, 7.79 mmol, 1.00 equiv) in DCE (300 mL) was added PPh3 (4.1 g, 15.63 mmol, 2.00 equiv). The solution was stirred for 1 h at room temperature under nitrogen. Then CCl4 (3.6 g, 23.38 mmol, 3.00 equiv) was added and the resulting solution was stirred at 72° C. overnight. After cooling, the resulting mixture was concentrated under vacuum. The residue was applied onto a silica gel column with ethyl acetate/petroleum ether (1:5 to 1:3) to give tert-butyl N-(2-[4-chlorothieno[2,3-d]pyrimidin-6-yl]ethyl)carbamate (1.0 g) as a light yellow solid. MS (ES): m/z 314 and 316 (M+H)+.
