反応手順

2,2-bis(methylol)propionic acid (bis-MPA) (22.1 g, 0.165 mol) was added in ethanol (150 mL) with Amberlyst-15 (6.8 g) and refluxed overnight. The resins were then filtered out and the filtrate was evaporated. Methylene chloride (200 mL) was added to the resulting viscous liquid to filter the unreacted reagent and by-products. The solution was dried over Mg504, filtered, and the solvent was removed in vacuo. Ethyl 2,2-bis(methylol)propionate was obtained as a clear and colorless liquid (21.1 g, 86% yield).
