Triethylamine → HCID 67041745, 화합물

Into a 250-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 2-(4-methoxybenzylamino)propan-1-ol (11 g, 56.41 mmol, 1.00 equiv) in dichloromethane (100 mL). This was followed by the addition of triethylamine (5.7 g, 56.44 mmol, 1.00 equiv). To this was added a solution of 2-bromoacetyl bromide (11.4 g, 56.44 mmol, 1.00 equiv) in dichloromethane (50 mL) dropwise with stirring at −17˜−25° C. The resulting solution was stirred for 1 h at −17˜−25° C. in a liquid nitrogen bath. The resulting mixture was washed with 3×100 mL of water. The organic layer was dried over anhydrous magnesium sulfate and concentrated under vacuum. This resulted in 16 g (90%) of N-(4-methoxybenzyl)-2-bromo-N-(1-hydroxypropan-2-yl)acetamide as yellow oil.
