PROCEDURE

实验过程

Sodium bromide (10.2 g; 0.1 mol) and 1,1-dichloro-N,N-dimethylacetamide (7.8 g; 0.05 mol) was added to dry dimethylformamide (100 ml) and the mixture was stirred for 4 h. Triethylamine (20.7 g; 0.2 mol) and trans-4-(tert.-butyloxycarbonylaminomethyl)cyclohexanecarboxylic acid (25.7 g; 0.1 mol) dissolved in dimethylformamide was added. The mixture was stirred for 84 h at 50° C. The solvent was evaporated and the residue was taken up into diethylether and washed, dried and evaporated. The oily residue was stirred with pentane. Yield 7 g, m.p. 110° C.
