This was followed by the addition of 30% sodium hydroxide solution [prepared by dissolving of 70.90 g (1.77 mol) of sodium hydroxide flakes/pellets in 235 ml of purified water] over a period of 15 minutes at 25 to 3O0C. Next, 50% of hydrogen peroxide (142.5 g, 2.095 mol) was added in 5 to 6 hours maintaining <n="16"/>temperature 25 to 35C under agitation. The reaction mixture was further stirred for 15 to 20 hours at 25 to 350C. After completion of the reaction (starting material should be less than 0.5% by area) toluene (1664 ml) was added and the reaction mixture was stirred for 10 minutes. The resulting biphasic mixture was acidified with concentrated hydrochloric acid (250 ml) under stirring while maintaining the temperature between 25 to 3O0C. The resulted mass further stirred at 25 to 3O0C for 1 hour. The precipitated product was collected by filtration, washed with water (3 x 832 ml) followed by toluene (416 ml) and dried to produce 416 g of 2-[(diphenylmethyl)sulfmyl] acetic acid as a white crystalline powder (Yield: 94.17%; HPLC Purity: 99.3% by area). | |

The monitoring of the sulfoxide formation was carried out by TLC (n-hexanes:EtOAc, 1:1 or CHCl3:MeOH, 9:1 as eluent). Aftercompletion of the reaction, the solvent was evaporated and the crude product waspuried by a recrystallization method (using EtOAC/n-hexane) (Table 2).
