実験手順
This method resulted in an improved yield of 85% when compared to the previous example (40%) yield by purification of compound 4 with column chromatography and by using H2/Raney Ni instead of BH3—SMe2. Further, the one-pot preparation of N′-(2-methoxy-4-methylbenzyl)-N2-(2-(5-methylpyridin-2-yl)ethyl) oxalamide shown in the previous example, was divided into two steps in this example. The yield was improved to 44% by purification of 2-(2-methoxy-4-methylbenzylamino)-2-oxoacetate in this example, from 30% yield without any purification of 2-(2-methoxy-4-methylbenzylamino)-2-oxoacetate in the one pot preparation described in the previous example.
