A flame dried flask was charged with TsOH (0.28 g, 1.63 mmol), ether (20 mL) and a stirbar under dry nitrogen atmosphere. To the stirred solution, MTBD (0.25 g, 1.63 mmol) was added. Instantly, a white precipitate formed and stirring was continued for 1 hour. The precipitate, 0.47 g (88%) of white salt, was then washed with excess ether and isolated by decantation. The salt was then dried under high vacuum.
