Participants

Reaction Steps

3.22 g (9.67 mmol) of 4-(4-chlorophenyl)-6-[3-(tetrahydro-2H-pyran-2-yloxy)propyl]pyrimidine, prepared in stage 5.3., are dissolved in 32 ml of methanol, and 16 ml of a 4N solution of hydrochloric acid in dioxane are added. The mixture is stirred at ambient temperature for 1.5 hours and then 150 ml of a half-saturated aqueous sodium hydrogencarbonate solution are added portionwise. Extraction is carried out with 350 ml of ethyl acetate. The organic phase is washed with 50 ml of water and 50 ml of a saturated aqueous sodium chloride solution, dried over sodium sulphate and evaporated to produce 2.33 g (9.36 mmol) of product in the form of a white solid.
