Dip pears into lemon juice. Heat wine, sugar and cinnamon stick in 10-inch skillet, stirring constantly, until sugar is dissolved and mixture boils; reduce heat and add pears. Simmer uncovered until pears are soft but not mushy when pierced with sharp knife, about 15 minutes
Cool pears in syrup until lukewarm; discard cinnamon stick. Remove pears to dessert dishes with slotted spoon. Spoon syrup over pears.
Serve warm or refrigerate until cool.
