実験手順: To an ice cold solution of 1.36 g (9.32 mmol) tetrahydro-thiopyran-4-carboxylic acid in 25 mL of dichloromethane (DCM) was added dropwise 1.1 mL (12.6 mmol) of oxalyl chloride, and the resulting mixture was stirred at 0° C. for 2 h. Then 2 μL of dimethylformamide (DMF cat) was added, and the reaction mixture was stirred at rt for 2 h, and concentrated to give 1.43 g (93%) of desired tetrahydro-thiopyran-4-carbonyl chloride as a brown oil as indicated by 1H NMR. The product was used without any further purification in the next step toward the preparation of 6-(4-Benzyloxy-phenyl)-7-(tetrahydro-thiopyran-4-yl)-3-(1H-tetrazol-5-yl)-pyrazolo[1,5-a]pyrimidine (below, entry 375). the reaction mixture was stirred at rt for 2 h concentrated
