73% | With sodium hydroxide; In tetrahydrofuran; at 20℃; for 24h;Cooling with ice; | To a magneticallystirred solution of valinol (4d, 2.0 g, 19.4 mmol) and 1 N NaOH (19.4 mL) inTHF (25 mL) in an ice bath, a solution of Boc2O (5.08 g, 23.3 mmol)in 15 mL of THF was added dropwise. The mixture reaction was stirred at roomtemperature for 24 h. Then, the solvent was evaporated under reduced pressureand the residue collected with EtOAc and washed with water and brine, dried (Na2SO4),and evaporated under vacuum to give 3.7 g of a white solid which wasrecrystalized from EtOAc/hexane to afford 2.85 g (73 %) of white crystals: mp 71-72 C; IR (KBr): 3419 (NH), 3274 (OH), 1683(CO); 1H NMR: delta 0.91 (d, J = 6.6Hz, 3H, CH3CHCH3),0.93 (d, J = 6.6 Hz, 3H, CH3CHCH3)1.42 (s, 9H, C(CH3)3),1.75-1.85 (m, 1H, CH(CH3)2),2.72-2.81 (m, 1H, exch D2O, OH), 3.35-3.45 (m, 1H, CH2CH),3.52-3.72 (m, 2H, CH2CH), 4.73 (d, J = 8.5 Hz, 2H,NH); 13C NMR: delta 18.7 (1C),19.7 (1C), 41.6 (1C), 28.6 (3C), 58.3 (1C), 64.3 (1C), 79.7 (1C), 157.1(1C); GC-MS (70 eV) m/z (%) 385 (M+ -31, 23), 57 (100); Anal.Calcd for (C10H21NO3): C, 59.08; H, 10.41; N,6.89.
