실험 절차

To a solution of 6-{[2-Chloro-3-(trifluoromethyl)phenyl]carbonyl}-3-iodo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine (40 mg, 0.09 mmol) in dichloroethane (1 mL) was added 3,4-dihydropyran (24 mL, 0.26 mmol) and para-toluenesulfonic acid (2 mg, 0.009 mmol). After stirring for 4 h at rt the reaction was diluted with CH2Cl2 and washed with aqueous saturated sodium bicarbonate. The organic layer was dried over anhydrous MgSO4, filtered and concentrated. Chromatography on silica gel (0-50% ethyl acetatehexanes) provided the desired product as a mixture of regioisomers (45 mg, 95%). MS (ESI) mass calcd. C19H18ClF31N3O2, 539.0. m/z found, 540.0 [M+H]+.
