実験手順
Excess phenylisocyanate (0.44 g) was added to a mixture of the product from Example 4 (0.60 g) in 100 mL EtOAc at room temperature. After sitting for a short period of time at room temperature, the solvent was removed in vacuo. EtOAc was added to the residue and allowed to sit 2 days at room temperature. The ethyl acetate was removed on the rotary evaporator. The residual solid was slurried in hexane/EtOAc, 1/1 and collected by filtration. (0.82 g) (100%). NMR (CDCl3) δ 1.06 (12H, d), δ 2.66 (2H, m), δ 4.24 (2H, s), δ 6.44 (1H, bs), δ 6.9-7.5 (18H, m), δ 7.93 (1H, bs). IR (KBr) 3391, 2964, 1648, 1531, 1444, 752, 700 cm-1.
