With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.720706-20-7,(4-Amino-4-tetrahydropyranyl)methanol,as a common compound, the synthetic route is as follows.
PREPARATION 9l-r(4-methylphenyl)sulfonyl]-6-oxa-l-azaspiror2.51octaneA solution of 4-aminotetrahydro-2H-pyran-4-methanol (16 g, 122 mmol) in dichloromethane (700 mL) was treated with triethylamine (85 mL, 610 mmol), p-toluenesulfonyl chloride (69.8 g, 366mmol) and DMAP (1490 mg, 12.2 mmol) under nitrogen. After approximately 18 hours at room temperature, the reaction was filtered through a pad of silica gel. The filtrate was concentrated in vacuo then purified by chromatography on silica gel (5-20% EtOAc/hexane) to afford intermediate the title compound (12.5g) as a white solid.1H NMR (CDCl3, 500 MHz, ppm) delta 1.92 (m, 2H), 2.08 (m, 2H), 2.47 (s, 3H), 2.52 (s, 2H), 3.76 (m, 2H), 3.99 (m, 2H), 7.35 (d, J=8.0 Hz, 2H), 7.86 (d, J=8.5 Hz, 2H)., 720706-20-7
720706-20-7 (4-Amino-4-tetrahydropyranyl)methanol 18316484, aTetrahydropyrans compound, is more and more widely used in various fields.
