Triethylamine → 4-(3-((Tert-butyldimethylsilyloxy)methyl)-4-nitrophenyl)morpholine

Participants

Reaction Steps

To a solution of (5-morpholino-2-nitrophenyl)methanol (3.0 g, 12.6 mmol), triethylamine (2.54 g, 25.2 mmol) and 4-dimethylaminopyridine (0.2 g) in dichloromethane (100 mL) was added tert-butylchlorodimethylsilane (2.83 g, 18.9 mmol). After the addition was over, the mixture was stirred at room temperature for 2 hours. The reaction mixture was diluted with ethyl acetate, and the organic phase was washed by saturated sodium bicarbonate, dried over anhydrous sodium sulfate, evaporated and purified by silica gel chromatography to afford the product 4-(3-((tert-butyldimethylsilyloxy)methyl)-4-nitrophenyl)morpholine (4.0 g, yield 90.9%).
