Practical and scalable syntheses were developed that were used to prepare multikilogram batches of GSK1292263A (<b>1b>) and GSK2041706A (<b>15b>), two potent G protein-coupled receptor 119 (GPR119) agonists. Both syntheses employed relatively cheap and readily available starting materials, and both took advantage of an Sb>Nb>Ar synthetic strategy.
