1-((2-Bromoethoxy)methyl)-4-methoxybenzene → HCID 67311654, compound

Participants

Reaction Steps

A mixture of 1-(2-bromo-ethoxymethyl)-4-methoxy-benzene (42 mg) and 1-phenyl-cycloheptanecarboxylic acid (R)-(1-aza-bicyclo[2.2.2]oct-3-yl)ester (Example 14e) (50 mg) in MeCN (1 mL) was stirred at room temperature for 16 h then heated to 80° C. under nitrogen overnight. A further 1.1 equivalents of 1-(2-bromo-ethoxymethyl)-4-methoxy -benzene were added and the mixture was heated at 80° C. for a further 48 h. The volatiles were evaporated and the crude product was purified by silica gel chromatography eluting with 0-10% of a 10% conc. NH3/MeOH solution in dichloromethane give 61 mg of an oil that was purified further by reverse phase HPLC (Gemini 5 μM C6 phenyl column) eluting with 5-95% MeOH/H2O containing 0.1% formic acid over 30 min with UV detection at 220 nm. The relevant fractions were combined and evaporated to afford the title compound (34 mg) as an oil.
