YieldReaction ConditionsOperation in experiment
2197 g A solution of <strong>[33024-60-1]tetrahydro-2H-pyran-4-amine hydrochloride</strong> (1.13 kg, 8.21 mol) in MeOH (14.3 L) is stirred at about 20 °C. then Et3N (1.06 kg, 1.43 L, 8.21 mol) is added. The mixture is stirred for at least 5 min then terephthalaldehyde diethyl acetal (1.43 kg, 6.84 mol) is added while maintaining the reaction temperature between 20-25 °C. The mixture is stirred for at least 45 min to form the imine. NaBH4 caplets (414 g, 11.0 mol) are added while maintaining the reaction temperature below about 25 °C. The mixture is stirred for 1 h after the addition is completed. The reaction mixture is quenched by adding 1 M NaOH (13.7 L) then extracted with MTBE. The organic solution was washed with brine (7.13 L) then dried (Na2S04) and concentrated to afford Compound A-2 (2197 g; 109percent yield, 94.4 area percent purity by HPLC) as a hazy oil. ?
