Reaction Steps

A mixture of (4S,7R)-1,7,8,8-tetramethyl-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (Intermediate 19; 100 mg, 0.49 mmol) and 2-trifluoromethyl-benzyl bromide (77 μL, 0.51 mmol) in N,N-dimethylformamide (5 mL) was heated at 100° C. overnight. The reaction mixture was evaporated and the residue was purified using a Biotage 40S system, eluting with 0-1% methanol/chloroform, followed by drying under high vacuum to give (4S,7R)-1,7,8,8-tetramethyl-2-(2-trifluoromethyl-benzyl)-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (55.3 mg, 32%) as a light yellow solid. APCI-MS (M+H) 365.
