Reaction Steps

5-(1-Aza-1-methylcyclohex-3-en-4-yl)-3-(2-pyrrolidinylethyl)-1H-indole: (17.6 mg, 13%) from 5-(1-aza-1-methyl-4-hydroxycyclohex-4-yl)-3-(2-pyrrolidinylethyl)-1H-indole (Example 13d, 145 mg, 0.44 mmol), triethylamine (0.95 mL, 6.8 mmol) and MsCl (0.25 mL, 3.2 mmol) in dichloromethane (3.5 mL) and THF (7 mL) with the exception that the reaction was carried out at a gentle reflux overnight and the extraction solvent consisted of a mixture of dichloromethane, chloroform, and ethyl acetate. Starting material (17 mg) was also recovered. The product in this case was converted to the hydrochloride salt which was soluble in methanol; HRMS-FAB+ for C20H27N3 : calculated MH+ :310.22833; found MH+ :310.22650.
