The chemical industry reduces the impact on the environment during synthesis 6346-09-4, name is 4,4-Diethoxybutan-1-amine, I believe this compound will play a more active role in future production and life. 6346-09-4
To a solution of commercially available 4-aminobutyaldehyde diethyl acetal (21)[1] (5.00 g, 31.0 mmol) in THF (75 mL) was added TEA (6.50 mL, 4.70 g, 46.5 mmol) at 0-5 C (ice-bath temperature). The mixture was allowed to stir for 5 min, and treated with a solution of Boc2O (6.76 g, 31.0 mmol) in THF (30 mL) drop-wise. The reaction mixture was stirred at 0-5 C for 30 min and allowed to warm to RT.and stir for 3 h. The mixture was transferred to a separatory funnel and partitioned with H2O (100 mL) and EtOAc (200 mL). The organic layer was separated, dried (anhydrous Na2SO4), filtered and concentrated to afford 7.71 g (95% yield) of compound 22 as a viscous slightly yellow oil: 1H NMR (400 MHz,CDCl3) delta 4.63 (bs, 1H), 4.46 (t, J = 5.39 Hz, 1H), 3.55 (ABq of q, J = 9.32, 7.14 Hz, Dn = 62.10 Hz, 4H), 3.12 (q, J = 6.40 Hz, 2H), 1.65 – 1.60 (m, 2H), 1.57 – 1.50 (m, 2H), 1.42 (s, 9H), 1.18 (t, J = 6.90 Hz, 3H). 13C NMR (100 MHz, DMSO-d6) delta 156.10, 102.47, 77.83, 60.99, (BocNHCH2- obscured by DMSO solvent peak ), 31.18, 28.78, 25.36, 15.83. HRMS ESI-TOF (m/z) = 284.1814 (284.1832 calculated for C13H27NO4Na) [M+Na].
