4-Methoxybenzyl alcohol → 7-Bromo-4-(4-methoxybenzyloxy)quinazoline

Participants

Reaction Steps

226.0 g (01.64 mol) of 4-methoxybenzyl alcohol in 0.5 l of toluene were added dropwise to a suspension of 80.0 g (2.0 mol) of sodium hydride [60% in paraffin oil] in 3.0 l of toluene between 15° C. and 20° C. The mixture was subsequently stirred at room temperature for a further 1 h. 165.9 g (1.64 mol) of 7-bromo-4-chloroquinazoline were then added in portions, and the reaction mixture was stirred for 48 h. Conventional work-up gave 194.8 g of 7-bromo-4-(4-methoxybenzyloxy)quinazoline as solid.
