Triethylamine → racemic trans-2-[1-(2-chlorophenyl)-2-(4-methoxyphenyl)-1,4,6,7-tetrahydro-5H-pyrrolo[3,2-c]pyridin-5-yl]cyclohexanol

Participants

Reaction Steps

A solution of 1-(2-chlorophenyl)-2-(4-methoxyphenyl)-4,5,6,7-tetrahydro-1H-pyrrolo[3,2-c]pyridine (Example 2, 500 mg, 1.33 mmol), cyclohexene oxide (1.34 mL, 13.3 mmol), and trietylamine (0.55 mL, 3.99 mmol) in ethanol (14 mL) was heated at reflux for 20 h. The solution was cooled to rt, and evaporated. The residue was purified by silica gel column, eluting with 3:1 to 2:1 hexanes:ethyl acetate. The product, racemic trans-2-[1-(2-chlorophenyl)-2-(4-methoxyphenyl)-1,4,6,7-tetrahydro-5H-pyrrolo[3,2-c]pyridin-5-yl]cyclohexanol, was isolated as a pale yellow solid (398 mg, 63%). LC-MS m/z (MH+) 437.1, retention time 2.45 min (method 1).
