A solution of 3-[(2-Azido-1-methyl-ethyl)-(4-methyl-cyclohexanecarbonyl)-amino]-5-phenyl-thiophene-2-carboxylic acid (8 mg, 0.19 mmol) in EtOH (0.2 ml) at 21°, was treated with 10% Pd/C (4 mg, 50% w/w) and stirred under an atmosphere of H2 for 1.5 h. The reaction mixture was filtered through a pad of celite with hot EtOAc and the combined filtrate and washings dried and evaporated to a glass to provide 3-[(2-Amino-1-methyl-ethyl)-(4-methyl-cyclohexanecarbonyl)-amino]-5-phenyl-thiophene-2-carboxylic acid (Compound 36). (7 mg, %); 1H NMR (300 MHz, Acetone-d6) 0.43-0.65 and 0.75-0.90 (m, 4H), 1.17-1.64 (m, 6H), 1.81-1.90 and 2.01-2.40 (m, 3H), 2.54 (bs, 1H), 3.00 (bs, 1H), 3.50 and 3.70 (bs, 1H), 7.20 (s, 1H), 7.22-7.25 and 7.29-7.34 (m, 3H), 7.58-7.62 (m, 2H).
