反応手順

A solution of 50 g of 3-aminotetrahydrofuran in 200 ml of dichloromethane was mixed with 63.8 g (0.63 mol) of triethylamine. 58.4 g (0.63 mol) of propionyl chloride were added dropwise with ice-cooling. The mixture was stirred at room temperature for 2 days, resulting in a white precipitate. The solution was filtered and the filtrate was distilled. B.p. 145° C. (12 mm), yield 81 g. 1H NMR (270 MHz, in CDCl3): δ=1.14 (t, 3 H), 1.83 (m, 1H), 2.22 (q, 2H), 2.31 (m, 1H), 3.64 (dd, 1H), 3.72-3.98 (m, 3H), 4.50 (m, 1H), 6.57 (s, 1H).
