실험 절차

To a mixture of 2-(4,4-dimethylcyclohexyl)-5-methyl[1,3]thiazolo[5,4-d]pyrimidin-7-ol (16.2 g) and toluene (160 mL) were added DMF (10 mL) and phosphorous oxychloride (11 mL), followed by stirring at 95° C. for 30 minutes. The reaction mixture was concentrated under reduced pressure. To the residue was added chloroform, and the mixture was neutralized with a 1 M aqueous NaOH solution in an ice bath and extracted with chloroform. The organic layer was dried over MgSO4 and then concentrated under reduced pressure. The residue was purified by silica gel column (hexane/EtOAc) to obtain 7-chloro-2-(4,4-dimethylcyclohexyl)-5-methyl[1,3]thiazolo[5,4-d]pyrimidine (13.2 g).
