Procedure

To a solution of 3-[1-benzoyl-2-pyrrolidinyl]phenol (0.69 g) in dry tetrahydrofuran (35 ml) was added methyl isocyanate (0.16 ml) followed by milled potassium carbonate (0.46 g) at ambient temperature, under nitrogen. The reaction mixture was stirred for 22 hrs, at which time it was filtered through a pad of celite, and the solids washed with ethyl acetate. The combined filtrates were concentrated. Recrystallization of the residue from ethyl acetate afforded 0.50 g (60%) of product, mp 117°-121° C.
