sounds a bit awkward to me. It sounds to me like "I bought a sandwich and went to the union." (parsed as ユニオンへ(サンドイッチを買って)行った。>> サンドイッチを買って、ユニオンへ行った might sound more natural but it also means "I bought a sandwich, and went to the union".)

買いに行った is like "went to buy" whereas 買って行った is like "bought and went".
