実験手順
The 4-[4-(6-chloro-2-naphthoyl)-1-piperidyl]-1-(4-fluorophenyl)-1-butanone prepared in Example 25 is dissolved in acetonitrile and 0.6 ml (9.2 mmoles) of methanesulfonic acid added. The mixture is stirred for 5 minutes and concentrated in vacuo and the residue stirred in anhydrous ether for 18 hours. The ether is decanted and the residue recrystallized from butanone and toluene to yield 4-[4-(6-chloro-2-naphthoyl)-1-piperidyl]-1-(4-fluorophenyl)-1-butanone methanesulfonate. M.P. 172°-5°.
