実験手順: General procedure Cwas applied to methyl 2-methoxybenzoate15c(66mg, 0.4mmol). The reaction mixture was stirredat room temperature for 16hours giving a conversion of >99% (GC-MS) and 16cand 17cin a 85:15mixture(1H NMR spectrum).

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: The title compound (430 mg) was prepared in four steps starting from 1.49 g (10 mmol) of 2-methylbenzothiazole and 1.66 g (10 mmol) of methyl 2-methoxybenzoate. After the reaction with hydrazine, the addition product was dissolved in methanol and heated to reflux with a catalytic amount of p-TSA (15 mg) for 2 hours to yield the title compound. MS (m/z, ES+): 308 (M+1, 100%). Yield=14%. heated to yield the title compound

実験手順: In agreement with this data the condensation of 2-methoxybenzoic acid methyl ester with acetonitrile using sodamide/liquid ammonia gives 2-methoxybenzoylacetonitrile in 84% yield, in contrast this same reaction using sodium hydride in benzene only leads to a 27.4% reaction yield.
