| titleOfInvention |
Process for the preparation, of 2-(2-hydroxyphenyl)-benz [1, 3] oxazin-4-one and its use for preparation of 4-[3, 5-bis (2-hydroxyphenyl)-lH-l , 2, 4-triazolTl-yl] benzoic acid |
| abstract |
The invention provides a novel process for the synthesis of 2-(2-hydroxyphenyl)-benz[1,3]oxazin-4-one, the process comprising of reacting the salicylic acid with salicylamide in the presence of p-toluenesulfonyl chloride, base and solvent. The use of 2-(2-hydroxyphenyl)-benz[1,3]oxazin-4-one in the preparation of Deferasirox is also disclosed in the invention. |
