Like with the previous solution use regular 1 way switches at both locations.
Use 1 wire between the locations to forward L from location 1 to location 2.
And use the other wire as the output from the switch in location 1 and connect it together with the output of the switch in location 2 to the SW1 input of the Dimmer 2 that is also located at location 2.
See attached diagram.
Thanks it's work ! ...

except that I plugged in a halogen of more than 250w, which put the dimmer in overload....
I just have to change the bulb
