反応手順

To a solution of methyl-{3-[4-((R)-methyl-1,2,3,4-tetrahydro-naphthalen-1-yl-carbamoyl)-thiazol-2-yl]-propyl}-carbamic acid tert-butyl ester (0.133 g, 0.3 mmol) was added a solution of 1M HCl in dioxane (0.65 mL) at RT. After stirring overnight at RT, the solvent was evaporated under reduce pressure. The resulting solid was triturated with diethylether, and filtered to give 2-(3-methylamino-propyl)-thiazole-4-carboxylic acid methyl-(R)-1,2,3,4-tetrahydro-naphthalen-1-yl-amide hydrochloride salt (0.097 g, 94%). 1H-NMR (400 MHz, CDCl3): δ=9.82-9.58 (br, 2H), 7.79 (s, 1H (conformers)), 7.12-7.03 (m, 4H), 5.43-5.54 (m, 1H (conformers)), 3.45-3.22 (m, 2H), 3.21-3.02 (m, 2H), 2.98-2.64 (m, 5H), 2.61-2.24 (m, 5H), 2.22-1.66 (m, 4H). MS: m/z=330 (M+1). MS: m/z=344 (M+1).
