実験手順
A mixture of 5-amino-4,6-dichloro-pyrimidine (5.0 g, 30.49 mmol) in acetone (30 mL) at 25° C. was treated with benzoyl isothiocyanate (5.5 g, 33.54 mmol). The mixture was stirred at reflux for 6 h and then was cooled to 25° C. The resulting solids were collected by filtration, washed with acetone and petroleum ether and dried in vacuo to afford N-(7-chloro-thiazolo[5,4-d]pyrimidin-2-yl)-benzamide (7.87 g, 79%) as an off-white solid. The NMR spectrum obtained on the sample is compatible with its structure.
