Reaction Conditions:
with chloro-trimethyl-silane in ethyl acetate at 70; for 2 h;
Steps:
4.3. Preparation of the catalyst
i. A mixture of 2,6-diisopropylaniline (33.9 mmol) and HOAc (1.18 mmol) and 15 mL MeOH was stirred in at 50 °C, then slowly dropwise added 15 mL of a MeOH solution of glyoxal (40% aqueous solution, 16.7 mmol) in 15 minutes. After the addition, the mixture continuing to stir at 50 °C for 30 minutes and then at room temperature for 10 hours. The reaction mixture was filtered dried to obtain 5.6 g of yellow compound a[57] (87% yield). ii. a (8.5 mmol) and paraformaldehyde (8.5 mmol) were added into 30 mL EtOAc and stirred vigorously to dissolve at 70 °C. Then, 20 mL of TMSCl (0.85 mmol) in EtOAc was slowly added dropwise to the reaction flask within 20 minutes. After reacting for 2 h, the reaction mixture is cooled to 10 °C and filtered. The filter cake was washed with EtOAc and dried to obtain 3.2 g of compound b[57] as a white solid (89% yield).
