Procedure

A 300 mL autoclave was charged with acetamide (VII)(11.8 g, 0.2 mole), 95% paraformaldehyde (13.6 g, 0.43 mole), acetic acid (10.6 g, 0.18 mole, 0.12 g/mL of DME), DME (90 mL) and Co2(CO)8 (4.1 g, 0.012 mole) and pressurized to 1500 psi (10,345 kPa) CO:H2 (95:5) at 25° C. This mixture was heated to 125° C. for 30 min. HPLC analysis of this stream indicated a 30% yield of (XVI) a 47% yield of (XVIII).
