実験手順

A solution of lactonitrile (378 g, 5.32 mol) in ethyl ether (1.46 L) and ethanol (0.34 L) was saturated with hydrogen chloride gas at 0-5° C. for 0.5 h and kept at 5° C. for 60 h. The resulting precipitate was filtered off and washed twice with ethyl ether to give the title compound of Preparation Twelve, Step A as a solid, 815 g (99%). mp: 165-168° C.; 1H NMR (CD3OD, 250 MHz) δ 1.45-1.53 (c, 6H), 4.40-4.61 (c, 3H).
