Patent ID: 8173844

Claim:
A process for preparing O-benzylated amino alcohols of the formula (I): the process comprising: reacting N-monosubstituted amino alkoxide salts with substituted or unsubstitued benzyl halides, the N-monosubstituted amino alkoxide salts being formed by deprotonation with an alkoxide, wherein n=0 and m=3 or 4, and R3, and R4 are H, R5 is a substituted and unsubstituted (C 1 -C 8 )-alkyl, (C 3 -C 8 )-cycloalkyl, (C 1 -C 8 )-alkyl-(C 3 -C 8 )-cycloalkyl, (C 3 -C 8 )-cycloalkyl-((C 1 -C 8 )-alkyl)1-3, (C 2 -C 8 )-alkenyl, (C 2 -C 8 )-alkynyl, (C 6 -C 18 )-aryl, (C 7 -C 19 )-aralkyl radical, (C 6 -C 18 )-aryl-((C 1 -C 8 )-alkyl)1-3, and Bn being a substituted or unsubstituted benzyl, and wherein the reaction is carried out in xylene, with the proviso that the process is carried out in the absence of alkali metal hydrides.
