Following a procedure similar to that described above in Example 111 but using m-toluyl chloride instead of o-toluyl chloride, there was obtained 14 g. of 3,4-bis(m-toluyloxy)phenyl tert-butylaminomethyl ketone hydrochloride as a white crystalline solid which melted at 215-218° C. When 19 g. of this hydrochloride (5 g. of which was obtained from a second run) was catalytically hydrogenated, using a procedure similar to that described above in Example 30B, there was obtained 3,4-bis(m-toluyloxy)-alpha-(tert-butylaminomethyl)benzyl alcohol hydrochloride which was converted to the free base and then to the methanesulfonate, a white crystalline solid which weighed 12.0 g. and melted at 135° C. (uncorr.).
