With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.33821-94-2,2-(3-Bromopropoxy)tetrahydro-2H-pyran,as a common compound, the synthetic route is as follows.

A mixture of D147 (1 .00 g, 5.02 mmol), 2-(3-bromopropoxy)tetrahydro-2H-pyran (1 .12 g, 5.02 mmol) and K2CO3(1 .39 g, 10.04 mmol) in DMF (20 mL) was heated at 80 C for 3 hrs. The reaction mixture was poured into ice water (60 mL), and extracted with EtOAc (2×30 mL). The organic layer was washed with brine (3×40 mL), dried, filtered and concentrated. The crude was purified by column chromatography on silica gel (PE: EtOAc= 1 : 1 ) to give the title compound as a yellow solid (1 .526 g, yield 89%).
