| abstract | PURPOSE: To obtain the titled compound in a high yield by reacting a cyanohydrin with formamide in the presence of an acidic catalyst and an ammonium salt as a co-catalyst with minimal occurrence of side reactions. n CONSTITUTION: In the presence of an acidic catalyst (e.g. inorganic acid organic carboxylic acid, sulfonic acid, or preferably 1-6C monocarboxylic acid-in particular, formic acid) together with an ammonium salt acting as a co-catalyst (the ammonium salt of the acid used as catalyst is suited.), a compound of formula I (R 1 and R 2 is H, 1-10C (hetero) aliphatic, 3-6C (hetero) alicyclic, 7-12C araliphatic, 4-12C heteroaraliphatic, 6-10C aromatic or 3-10C heteroaromatic radicals) are reacted with a compound of formula II at a temperature of 20-150°C, more preferably 80-100°C to form a compound of formula III. To one mole of the formula I compound, 1.2-1.8 moles of the formula II compound, and 0.1-0.3 mole of the acid and of the ammonium salt are preferably used. n COPYRIGHT: (C)1992,JPO |
