Procedure

1-[4-(4-methoxyphenoxy)phenyl]ethan-1-one (1 mmol) was brominated by General Procedure R1. The bromo ketone was condensed with 7-amino-2-Boc-1,2,3,4-tetrahydroisoquinoline following general procedure R2. The aminoketone intermediate was treated with n-pentanoyl chloride accoding to General Procedure R3. The product amide was then subjected to imidazole formation employing general procedure R4. The BOC group of the product was removed employing general procedure T1 to afford 7-{2-butyl-4-[4-(4-methoxy-phenoxy)-phenyl]-imidazol-1-yl}-1,2,3,4-tetrahydro-isoquinoline hydrochloride (yield 135 mg)

Workup

customThe BOC group of the product was removed
