実験手順
A solution of 2-bromophenyl isocyanate (Aldrich Chemical Company) (27.4 ml, 0.222 mol) in dry diethyl ether (65 ml) was added dropwise over 0.5 h to an efficiently stirred solution of D2 (51.4 g, 0.222 mol) in dry diethyl ether (0.8 L) under argon at ambient temperature. After stirring for 18 h, a white precipitate was filtered off and washed with dry diethyl ether (2×150 ml). The solid was crushed to a fine powder and then re-stirred with diethyl ether (470 ml) for 4 h at ambient temperature. The insoluble product was filtered off, washed with diethyl ether (100 ml) and dried at 50° C./vacuum/24 h to afford title compound as a white solid.
