936130-82-4, Methyl 4-(piperidin-4-yl)benzoate hydrochloride is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Water (0.2 mL), paraformaldehyde (0.470 g, 15.64 mmol) and acetic acid (0.895 mL, 15.64 mmol) were added to a stirred suspension of 4-(4-(methoxycarbonyl)phenyl)piperidinium chloride (1 g, 3.91 mmol) in THF (20 mL) under nitrogen. Sodium cyanoborohydride (0.369 g, 5.87 mmol) was added portionwise over a period of 10 mins. The resulting mixture was stirred at 60 C. for 19 h. The reaction mixture was evaporated to dryness and mixed with water (20 mL) and 1M HCl (5 mL). The solution was washed with EtOAc (2×15 mL), basified with K2CO3 and extracted with EtOAc (2×15 mL). The organic layer was washed with saturated brine and dried over MgSO4, filtered and evaporated to afford pure methyl 4-(1-methylpiperidin-4-yl)benzoate (0.459 g, 50.4%)as a colourless oil which crystallised on standing. 1H NMR (399.9 MHz, DMSO-d6) delta 1.63-1.72 (2H, m), 1.73-1.77 (2H, m), 1.96-2.03 (2H, m), 2.21 (3H, s), 2.87-2.90 (2H, m), 3.85 (3H, s), 4.30-4.31 (1H, m), 7.40 (2H, d), 7.88-7.91 (2H, m)
936130-82-4, As the paragraph descriping shows that 936130-82-4 is playing an increasingly important role.
