To the reaction mixture was added dropwise chloroacetyl chloride (2.5 g; 0.022 mole) and the resulting mixture was stirred for 10 minutes. The layers were separated and the organic methylene chloride layer was washed with water, dried over magnesium sulfate and concentrated in vacuo to yield a crude product. The crude product was separated on a silica gel column using a 2:5 ethyl acetate:cyclohexane mixture as the eluant to yield N-2-methylethyl-N-[6-methyl-2-(2-(2-methoxyethoxy)ethoxy)phenyl]acetamide (Compound No. 102) (2.7 g; 39% yield) as a clear yellow oil having a boiling point of 163° C. (0.13 mmHg) and the following analysis:
