Reaction Steps

To a solution of the above 2-benzyloxy-carbonylamino-5-(S)-(1,3-dioxo-1,3-dihydro-isoindol-2-ylmethyl)-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester hydrochloride (42 mg, 0.072 mmol) in ethanol (0.5 ml) was added hydrazine (68 μl, 0.22 mmol). The solution was stirred at 80° C. for 5 hours and at room temperature for 16 hours. The mixture was filtered and the filtrate evaporated in vacuo. The residue was extracted with dichloromethane (5×1 ml). The combined dichloromethane washes were evaporated in vacuo affording 20 mg (67%) of 5-(S)-aminomethyl-2-benzyloxy-carbonylamino-4,5,6,7-tetrahydro-thieno[2,3-c]pyridine-3-carboxylic acid tert-butyl ester as an oil.
