Water → 2-Tert-butyl-4-chloro-6-cyclobutyl-pyrimidine

Participants

Reaction Steps

9.9 g of 2-tert-butyl-4-hydroxy-6-cyclobutyl-pyrimidine (48 mmol) were dissolved in 80 ml of toluene and 1 ml of dimethylformamide. 10.7 ml of POCl3 (114.8 mmol) were added dropwise at 10° C. Stirring was continued for 3 h at room temperature. The reaction mixture was poured into water, and the aqueous layer extracted with dichloromethane. The organic layer was dried over magnesium sulfate, filtered, and then concentrated to dryness to give 10.8 g of a yellowish oil (quant.).
