And the patent contained the following:
The title compounds I [R1 = OR4, S(O)tR5; t = 0-2; R2 = H, alkyl; alkyl-O-alkyl, alkylaryl, etc.; R4 = alkyl-O-alkyl, alkylaryl, etc.; R5 = alkyl, alkyl-O-alkyl; R10, R11 = H, halo, alkyl, etc.] which are ERK inhibitors useful in treating cancer, were prepared E.g., a multi-step synthesis of (1R)-II, starting from Me 4,6-dichloropyridine-3-carboxylate and hydrazine, was described. Exemplified compounds I were tested in human ERK2 activity assay (data given). Pharmaceutical compositions comprising compound I, alone or in combination with an effective amount of at least one chemotherapeutic agent, were disclosed. The experimental process involved the reaction of 5-Methoxy-1H-pyrazole(cas: 215610-30-3).Electric Literature of 215610-30-3
