Participants

Reaction Steps

To a stirred suspension of 2.37 g sodium hydride in 45 ml tetrahydrofurane are added portionwise at room temperature 13.32 g 1-isopropyl-7-methyl-4a,5,6,8a-tetrahydro-2,4-(1H)-quinazolindione and the mixture stirred for 45 minutes. 39 ml of a 2N solution of 4-fluorophenyl magnesium bromide in tetrahydrufurane are then added dropwise within 2 hours at an internal temperature of 40° and the resulting suspension stirred at 40° for 15 hours. 23 ml 15% hydrochloric acid are then added under ice cooling and the solvent removed in vacuo. The residue is taken up with water and methylene chloride. The methylene chloride phase is evaporated to dryness to obtain the title compound.
