M would be the acyl chloride I've drawn. Then we add 2 equivalents of diazomethane. The first equivalent will give the compound M-N (addition to carbonyl, chlorine leaves, and then attacks the new carbon liberating nitrogen gas). Now is when the trouble starts. I see quite a few ways ...

NaHCO3solution and extracted with EtOAc. The combined organic layers were washed with aqueous NH4Cl solution, dried over Na2SO4, and evaporated to dryness under reduced pressure. The residue was purified by flash column chromatography on silica gel to afford the corresponding γ-alkynylated ketone5...

(2b,2k,2w, and2x), a carbamate (2c), an amide (2d), a trifluoromethyl group (2j), aryl fluorides (2n,2z), as well as a ketal (2x), are all readily accommodated. Notably, sensitive functional groups such as an easily reduced aldehyde (2l) and ketone (2m,2z), a chloride (2o...
methyl ethyl ketone, and mixtures of such solvents. The reaction temperatures are between 0° and 180° C., preferably between 20° C. and 120° C. It is often advantageous to use acid acceptors or condensation agents. Suitable examples are: tertiary amines, e.g. trialkylamines (e.g. ...
A solution of oxalic acid (152.4 g, 1.693 moles, 2.2 equivalents) in methylisobutyl ketone (2300 ml) was added slowly with stirring to a solution of Intermediate 4 (214.3 g, 0.77 moles, 1 equivalent) in methylisobutyl ketone (800 ml) at room temperature. The resulting mixture was stirred...
