Procedure

Formaldehyde (4.08 g, 50.2 mmol) and methanol (2.032 mL, 50.2 mmol) were combined, and the mixture was cooled to 0° C. (ice bath). N-(3-(trifluoromethyl)benzyl)-1-(trimethylsilyl)methanamine (10.94 g, 41.9 mmol) was added dropwise via addition funnel over 30 minutes. Potassium carbonate (4.63 g, 33.5 mmol) was added, and the reaction stirred at 0° C. for 2 additional hours. The reaction product was decanted from the potassium carbonate, treated with more potassium carbonate, and decanted again. The potassium carbonate solids were washed several times with ether, and these washes were added to the product solution. The solvent was removed in vacuo to give 1-methoxy-N-(3-(trifluoromethyl)benzyl)-N-((trimethylsilyl)methyl)methanamine which was used directly in the next step.
