Reaction Steps

A18 was prepared in an manner analogous to example A1 with the exception that in step A1.1 4-aminosulfonylbenzylamine hydrochloride was substituted for 4-methylsulfonylbenzylamine hydrochloride, and in step A1.2 ethyl 4-aminobenzoate was substituted for ethyl 2-amino-4-methyl-5-thiazole carboxylate. The product was purified by preparatory reverse phase HPLC to yield A18 in 21% yield. LCMS=Ret. Time=2.87 min*, M+=538.40. * HPLC conditions used to determine retention times; 4 min gradient 0–100% B in A(A; 0.1% TFA in 90/10 water/methanol; B; 0.1% TFA in 10/90 water/methanol) using a YMC ODS S5 column at 220 nm.
