Versuchsvorschrift
(R)-tert-butyl 1-(4-fluorophenyl)-4a-picolinoyl-4a,5,7,8-tetrahydro-1H-pyrazolo[3,4-g]isoquinoline-6(4H)-carboxylate (180 mg, 0.39 mmol) was dissolved in HCl-dioxan (4 M, 4 mL) and the resultant solution was stirred vigorously at room temperature for 1.5 hours. The reaction mixture was evaporated to afford (R)-(1-(4-fluorophenyl)-4,4a,5,6,7,8-hexahydro-1H-pyrazolo[3,4-g]isoquinolin-4a-yl)(pyridin-2-yl)methanone as a yellow solid. LCMS (Method B, ESI): RT 0.30 and 2.01 min, m+H=375.2.
