Procedure

A 300 mL autoclave was charged with acetamide (VII)(11.8 g, 0.2 mole), 95% paraformaldehyde (13.6 g, 0.43 mole), water (12.9 g, 0.72 mole), acetic acid (2.1 g, 0.035 mole), acetone (90 mL) and Co2(CO)8 (2.1 g, 0.006 mol) and pressurized to 3200 psi (22,069 kPa) CO:H2 (95:5) at 25° C. This mixture was heated to 110° C. for 30 min. HPLC analysis of this stream indicated a 95% yield of (XVI), 0.5% (XIV), and 4.5% (XVIII).
