The invention provides the use of a B-subgroup metal oxide alkylation catalyst in alkylating an amino or amido group-containing compound using an ether alkylation agent. Thus, amines and amides may be N,N-cyclodialkylated by reaction with an unstrained cyclic ether in the presence of a B-subgroup metal oxide alkylation catalyst, preferably a Group IV-B metal oxide such as titanium dioxide.
A compound of the formula (I):
wherein:
A and B together represent an optionally substituted, fused aromatic ring; X and Y are selected from CH and CH, CF and CH, CH and CF and N and CH respectively; R
C
is selected from H, C
1-4
alkyl; and R
1
is selected from C
1-7
alkyl, C
3-20
heterocyclyl and C
5-20
aryl, which groups are optionally substituted; or R
C
and R
1
together with the carbon and oxygen atoms to which they are attached form a spiro-C
5-7
oxygen-containing heterocyclic group, which is optionally substituted or fused to a C
5-7
aromatic ring.

The present invention is a method for producing a cyclopentyl alkyl ether compound represented by formula (1): R1-O-R2 (wherein, R1 represents an alkyl group having 1 to 10 carbon atoms that may have a substituent or a cycloalkyl group having 3 to 8 carbon atoms that may have a substituent, and R2 represents a cyclopentyl group that may have a substituent), wherein a cyclopentene that may have a substituent is reacted with an alcohol compound represented by formula (2): R1OH (wherein R1 represents the same as described above) in the presence of an acidic zeolite having a silica/alumina ratio of 80 or higher. The present invention provides a method for producing a cyclopentyl alkyl ether compound, wherein a reaction can be carried out in a liquid phase, catalyst activity is less lowered over time (long catalyst life), and a desired cyclopentyl alkyl ether compound can be continuously produced with high reaction efficiency and long-term stability even when a large amount of raw material is fed.
