Synthetic Route of 54314-84-0,Some common heterocyclic compound, 54314-84-0, name is ((3-Bromopropoxy)methyl)benzene, molecular formula is C10H13BrO, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
26.1.N-[3-(benzyloxy)propyl]-6-chloro-N-cyclopentylpyridine-3-sulfonamideA mixture of 1 g (3.84 mmol) of 6-chloro-N-cyclopentylpyridine-3-sulfonamide, 1.32 g (9.59 mmol) of K2CO3 and 0.88 mL (4.99 mmol) of [(3-bromopropoxy)methyl]benzene in 8 mL of anhydrous DMF is heated for 12 hours at 40° C.After cooling to room temperature, the medium is taken up in 300 mL of EtOAc, washed successively with water (2*100 mL), saturated NaHCO3 solution (100 mL) and brine (100 mL), dried over Na2SO4 and then concentrated under reduced pressure and purified by chromatography on a column of silica gel, eluting with a cyclohexane/EtOAc gradient of 0 to 10percent EtOAc.1.65 g of N-[3-(benzyloxy)propyl]-6-chloro-N-cyclopentylpyridine-3-sulfonamide are thus obtained in the form of an oil.Yield=99percent.1H NMR, CDCl3, 400 MHz, delta (ppm): 8.85 (s, 1H); 8.1 (d, 1H); 7.5 (d, 1H); 7.4-7.3 (m, 5H); 4.5 (s, 2H); 4.2 (m, 1H); 3.6 (t, 2H); 3.2 (dd, 2H); 2.1 (m, 2H); 1.6-1.3 (m, 8H)
The synthetic route of 54314-84-0 has been constantly updated, and we look forward to future research findings.
