Preparation of N-acylcarboxamide derivatives using acidic catalysts under a mild condition

Preparation of N-acylcarboxamide derivatives using acidic catalysts under a mild condition. (Dainippon Ink and Chemicals, Inc., Japan). Jpn. Kokai Tokkyo Koho JP 09012527 A2 14 Jan 1997 Heisei, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C07C271-64. ICS: B01J031-02; B01J031-04; C07C269-06; C07B061-00; C08F020-36. APPLICATION: JP 1996-71649 27 Mar 1996. PRIORITY: DE 1995-19523124 26 Jun 1995. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Claimed is a process for prepn. of the title compds. (R3CONR1CO2)nR2 [R1 = H, univalent aliph. or arom. radical, etc.; R2 = univalent or multivalent (un)satd. aliph. or arom. radical, etc.; R3 = univalent (un)satd. aliph. or arom. radical, etc.; n = 1-4] by reacting carboxamides (HNR1CO2)nR2 (R1, R2 = same as above) with anhydrides (R3CO)2O (R3 = same as above) in the presence of stronger org. acids. The title compds. are prepd. at lower temp.In this experiment, several chemicals are used like 622-46-8 in an industrial manner efficiently, easily, and economically. Thus, H2NCO2Me was reacted with Ac2O in the presence of p-TsOH to give the title compd. MeCONHCO2Me. .
