実験手順

Intermediate I was prepared in the same manner as Intermediate B, using 3-morpholinecarboxylic acid as the starting material instead of (R)-2-aminobutanoic acid. No reductive amination step, such as that used for the conversion of compound II to compound III, was required. Rather, methylmorpholine-3-carboxylate was reacted directly with 2,4-dichloro-5-nitropyrimidine in the same manner as is described for the conversion of compound III to Intermediate A. LCMS: 254.9 m/z (M+H)+.
