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 benzyl bromide (52 μL, 0.44 mmol) in N,N-dimethylformamide (4.5 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)-2-benzyl-1,7,8,8-tetramethyl-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (71.5 mg, 55%) as an off-white solid. APCI-MS (M+H) 297.
