Sodium Hydroxide → HCID 57144728, compound

Participants

Reaction Steps

10 g of 2,4-bis-butylamino-6-(2,2,6,6-tetramethyl-4-benzoyloxypiperidin-1-yl)1,3,5-triazine (prepared according to Example 8) are heated at reflux for 6 hours with 50 ml of methanol and 50 ml of twenty per cent sodium hydroxide solution. The methanol is distilled off from the reaction mixture in vacuo. 100 ml of toluene and 50 ml of water are added to the residue, shaken thoroughly, the aqueous phase is separated off and the toluene solution is washed three times, each with 50 ml of water. After evaporating the toluene solution, 2,4-bis-butylamino-6-(2,2,6,6-tetramethyl-4-hydroxypiperidin-1yl)-1,3,5-triazine is obtained as a yellowish viscous material. Colorless crystals which melt at 90° C. are obtained by crystallization from acetonitrile.
