Cron to find exec cp and redirect output with time / date per line?

I try to setup a cron task to run a set of basic shell commands. I need to look to any files created on the last day, then copy to another folder and generate a log stating, line by line, the date and the time of the file copy operation. The two shell commands run separately but need to create one and schedule via cron. When I try to increase the first command (find) cron does not execute the task and gives errors. If I run manually, it works. find /dir/ -type f -mtime -1 -exec cp -v -a --parents "{}" /dir2/ \; >> /dir2/LogsCopiaDBs_$(date +%d-%m-%Y).txt exec &> >(while read line; do echo "$(date +'%h %d %Hh%Mm%Ss') $line" >> /dir2/LogsCopiaDBs.txt; done;) Any idea ?
