YieldReaction ConditionsOperation in experiment
95% With lithium aluminium tetrahydride In tetrahydrofuran; diethyl ether at -15 - -10℃; for 2.16667 h; Inert atmosphere To a solution of ethyl l-((ieri-butoxycarbonyl)amino)cyclobutanecarboxylate (2.97 g, 12.2 mmol) in diethyl ether (50 mL) at -15 °C under nitrogen was added dropwise lithium aluminium hydride (12.8 mL, 25.6 mmol, 2.0 M in THF) over 40 min. The reaction was maintained at -10 °C for 1.5 h then quenched with water (4 mL), 2 N NaOH (5.4 mL) then more water (11 mL). The reaction was warmed to r.t. and stirred for 30 min then MgS04 was added and the reaction was filtered through Celite, washing well with ethyl acetate. The filtrate was concentrated to yield the title compound as an off white solid (2.34 g, 95percent).

Stage #1: With hydrogenchloride In ethanol; water at 20℃; for 8 h; Reflux; Inert atmosphere
Stage #2: With sodium hydrogencarbonate In water; ethyl acetate at 20℃; for 12 h; Inert atmosphere
General procedure: 6 M aqueous HCl (2 ml) was added to asolution of oxazoline 2c (0.158 g, 0.58 mmol) in EtOH(2 ml), and the mixture was stirred for 1 h at roomtemperature, then it was refluxed for 7 h. The solvents wereremoved in vacuo, and saturated aq NaHCO3 solution(10 ml) was added to the residue followed by di-tert-butyldicarbonate (0.275 g, 2.00 mmol) solution in EtOAc(10 ml). The reaction mixture was stirred for 12 h at roomtemprature. The organic phase was separated, and theaquoeus phase was extracted with EtOAc (3 × 10 ml). Thecombined, organic phases were washed with saturated aqNaCl (10 ml) and dried over Na2SO4. The extract wasevaporated and the residue was purified by flash chromatography on silica gel (eluent EtOAc – light petroleum ether,gradient from 1:4 to 1:1).
