実験手順
(R)-2-Chloro-N-(2,3-dihydroxypropyl)acetamide (1.31 g, 8.20 mmol) in tert-amyl alcohol (34 mL) was added dropwise over 2 h to a stirred solution of potassium tert-butoxide (2.30 g, 20.6 mmol) in tert-amyl alcohol (16 mL) at room temperature under nitrogen. After 1 hr, MeOH (8 mL) and water (0.5 mL) were added and the reaction mixture was stirred for an additional 20 min. The mixture was concentrated under vacuum and purified by flash column chromatography on silica gel, eluting with methanol/ethyl acetate (2/8) to give the title compound as a white solid (0.59 g, 54%).
