Chem. 1978.1194) are added. The reaction mixture is heated to 160° C., until there is no further reaction, and after cooling evaporated to dryness. The residue is combined with ice water. The product is extracted with dichloromethane and purified by chromatography. 125 mg (III-8) are obtained as a solid. Analytical HPLC-MS (method A): RT=1.08 min.
