represents an alkyl group, R
2
represents an alkyl group having carbon atom(s) of 1 to 10, a haloalkyl group having carbon atom(s) of 1 to 10, or an aryl group having carbon atoms of 6 to 10 optionally substituted by an alkyl group having carbon atom(s) of 1 to 10, and when R
2
represents the alkyl group, R
1
and R
2
are optionally the same or different each other.) to any of the following reactions a), b) and c):
