Mix jam, orange peel, brandy, lemon juice and cinnamon in a shallow microwave-safe serving dish just large enough to also hold the brie.
Set brie in apricot sauce. Return to microwave oven and cook, uncovered, until the cheese is hot and slightly melted, about 1 minute; check at 20-second intervals.
Scoop cheese and apricot sauce onto the baguette slices.
