Reaction Steps
A mixture of a (4S,7R)-2-(2-fluoro-phenyl)-7,8,8-trimethyl-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (Intermediate 12; 150 mg, 0.52 mmol) and 1-iodopropane (103 μL, 1.05 mmol) in N,N-dimethylformamide (2 mL) in a microwave reaction tube was heated to 100° C. and stirred for 18 h. The reaction mixture was allowed to cool, diluted with saturated sodium bicarbonate, and extracted twice with ethyl acetate. The organic extracts were combined, washed with water and brine, dried (magnesium sulfate), filtered, evaporated, and purified using an ISCO CombiFlash® Sg100c chromatography system with an Isco 12 g column, eluting with 25-100% ethyl acetate/hexanes to give (4S,7R)-2-(2-fluoro-phenyl)-7,8,8-trimethyl-1-propyl-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (59.7 mg, 35%) as an orange oil. ES(+)-MS (M+H) 329.
