bis(2-methylphenyl)methanone

Conditions: temp:25.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Step 2 Under anhydrous conditions benzothiazole was dissolved in THF (0.35 M). At −78° C. added BuLi (1.1 eq). After 1 h at −78° C., added the amide from step 1 in THF, over 15 min. The reaction was allowed to warm to 25° C. After stirring at 25° C. for 1 day, workup with ethyl acetate and water and chromatography afforded pure tolyl ketone product (52%). over 15 min

Procedure: Step 5 Under anhydrous conditions the benzothiazole acid (step 4) was dissolved in THF (0.052 M). At −78° C. added BuLi (2.2 eq). After 1 h at −78° C. to 0° C., added the amide (1.28 eq) from step 1 of Example 81, in THF, at −78° C., over 5 min. After 0.5 h at −78° C., the reaction was allowed to warm to 25° C. After stirring at 25° C. for 2 h, workup with ethyl acetate and water and chromatography afforded pure tolyl ketone acid product (64%). After 0.5 h at −78° C.
