4-Methoxybenzyl bromide → HCID 57941414, compound

Participants

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; 102 mg, 0.49 mmol) and 4-methoxy-benzyl bromide (73 μL, 0.50 mmol) in N,N-dimethylformamide (5 mL) was stirred at room temperature overnight, then heated to 100° C. and left over the weekend. At this time it was found that the heating bath had failed and the reaction mixture was at room temperature. 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-(4-methoxy-benzyl)-1,7,8,8-tetramethyl-1,2,4,5,6,7-hexahydro-4,7-methano-indazol-3-one (48 mg, 30%) as a white solid. APCI-MS (M+H) 327.
