Downstream synthetic route of 3202-33-3

3202-33-3, 3202-33-3 4-Phenoxypiperidine 18878, apiperidines compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.3202-33-3,4-Phenoxypiperidine,as a common compound, the synthetic route is as follows.

To a solution of 4-phenoxypiperidine (500 mg, 2.82 mmol) in DMF (6 mL) was added K2CO3 (0.78 g, 5.64 mmol) and 2-bromoethanol (0.39 g, 3.1 mmol). The reaction mixture was heated to 50C and stirred at that temperature for 3 h. TLC showed most of the product. The reaction was poured into water and extracted with DCM (3 x 40 mL). The combined organics were washed with saturated aqueous NaCl (2 x 20 mL). The combined organics were dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The resulting oil was purified by flash column chromatography with a gradient elution of DCM (95%) and MeOH (5%) to DCM (85%) and MeOH (15%) to provide 2-(4- phenoxypiperidin-1-yl)ethanol (260 mg, 1.17 mmol) as a yellow solid.

3202-33-3, 3202-33-3 4-Phenoxypiperidine 18878, apiperidines compound, is more and more widely used in various fields.
