The best time to take cuttings of any plant is to wait until the flowers
have expired. The reason is that the plant will put its energy into the
flower rather than to the direction of root initation.  The principle is
called a "sink".

Wait until the new growth has hardened about a month or so after leaf
initation.
Take the cuttings 6-8 inch long.
Store in a poly bag for a day until callous.
Use a dry powder rooting hormone at about 0.1%IBA such as Rhizopon AA #1
(from V-J Growers Supply 800-327-5422).
Cover completely with clear poly bag.
Root initation should occur in 10-20 days.

Another easy way is to groung layer.
Take a young branch from the lower portion of the plant ... dip it down to
the soil ... at the point of 'landing' make a wound in the bark ... push
down into the soil and use a rock to hold it down.
Rooting can be rapid but wait a couple of months before you inspect the new
roots. Best to wait until the fall to cut off and replant. Lilac are a bit
tricky to replant during the mid season.
