Procedure

To a solution of 240 mg. of the product of Example 2 (prepared as described) in 15 ml. of acetonitrile is added a solution of 0.30 ml. of triethylamine in 5 ml. of acetonitrile. The reaction mixture is stirred at room temperature for 4 hours then is cooled in an ice bath. The precipitate is collected by filtration to give 136 mg. of the desired crude product as orange crystals, mp. 224°-228° C.
