With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.134441-61-5,(R)-N-Boc-Piperidine-2-methanol,as a common compound, the synthetic route is as follows.
Trifluoroacetic acid (3 ml) was carefully added to a stirring solution of tert-butyl (2R)-2- (hydroxymethyl) PIPERIDINE-L-CARBOXYLATE (1.15 g, obtained as described in TETRAHEDRON, 5 8 (2002), 1343-1354) in DCM (3 ml) and stirred at room temperature for 1 hour. Volatiles were removed IN VACUO and the oil thus obtained dissolved in methanol (60 ml), and neutralized by addition of MP-Carbonate resin (polymer supported carbonate reagent ex. Argonaut Technologies Inc.) (approximately I g) whilst stirring at room temperature for 2 hours. The resin was filtered, washed with methanol (3 x 30 ml) and the filtrate concentrated. The resulting oil was dissolved in DCM (30 ml) and dried (MgSO4) before filtration and solvent removal to afford a grey oil (615 mg, 100%); NMR spectrum (DMSO-D6) 1.44-1. 51 (m, 2H), 1.61 (m, 1H), 1.70-1. 78 (m, 3H), 2.84 (m, 1H), 3.03 (m, 1H), 3.21 (d, 1H), 3.49 (m, 1H), 3.57 (dd, 1H), 5.01 (bs, 1H), 7.65 (bs, 1H) ; Mass spectrum M+ 116., 134441-61-5
The synthetic route of 134441-61-5 has been constantly updated, and we look forward to future research findings.
