PROCEDURE

实验过程

The 4-chloro-N-{2-[2-(3-hydroxyphenyl)-1-pyrrolidinyl]ethyl}benzamide (0.29 g) was dissolved in tetrahydrofuran (20 ml), and methyl isocyanate (50.0 μl) and milled potassium carbonate (0.17 g) at ambient temperature were added, under nitrogen. The reaction mixture was stirred for 2 hrs and filtered through a pad of celite. The filter cake was washed with ethyl acetate, and the combined filtrates were concentrated. Crystallization of the residue with ether/petroleum ether gave 0.32 g (94%) of product. Recrystallization from ether gave the analytical sample, mp 103°-106° C.
