Reaction Steps

A suspension of 2-[N-Boc(amino)]-5-vinyl-4-diethylphosphonomethoxycarbonyl thiazole (1 mmole) and 10% Pd/C (0.5 mmole) in MeOH (5 mL) was stirred under an atmosphere of H2 (balloon) at room temperature for 15 h. Filtration and evaporation gave 2-[N-Boc(amino)]-5-ethyl-4-diethylphosphonomethoxycarbonylthiazole as a yellow solid, which was subjected to Step D of Example 18 followed by Step C of Example 3 to give 2-amino-5-ethyl-4-phosphonomethoxycarbonylthiazole (18.3) as a solid. Mp>230° C. (decomp). Anal. Calcd. for C7H11N2O5PS: 31.58; H, 4.16; N, 10.52. Found: C, 31.80; H, 4.04; N, 10.18.
