Reaction Steps
A 300 mL autoclave was charged with N-acetylglycine (XVIII)(23.4 g, 0.20 mole), 95% paraformaldehyde (6.8 g, 0.22 mole), water (6.5 g, 0.36 mole), acetic acid (16.8 g, 0 28 mole), DME (90 mL), and Co2 (CO)8 (2.01 g, 0.006 mole) and pressurized to 1500 psi (10,345 kPa) CO:H2 (95:5) at 25° C. This mixture was heated to 110° C. for 30 min. HPLC analysis of this stream gave an 87% yield of (XVI), 1.0% (XIV), and 10% unreacted (XVIII).
