| titleOfInvention | Improved process for the synthesis of diesters of phosphoric acid 2,5-dioxo-4,4-diphenyl-imidazolidin-1-ylmethyl ester |
| abstract | PCT No. PCT/US97/05307 Sec. 371 Date Oct. 15, 1998 Sec. 102(e) Date Oct. 15, 1998 PCT Filed Apr. 1, 1997 PCT Pub. No. WO97/41132 PCT Pub. Date Nov. 6, 1997An improved process for the preparation of a diester of phosphoric acid 2,5-dioxo-4, 4-diphenyl-imidazolidin-1-ylmethyl ester is described where an alkali metal phosphate is treated with a 3-(chloromethyl)- or 3-(bromomethyl)-5,5-diphenyl-2,4-imidazolidinedione to afford the desired product, as well as valuable intermediates used in the process. |
