Versuchsvorschrift
Step C Hydrolysis: To a solution of 7-Cyclohexylamino-1-ethoxycarbonylmethoxy-3,8-dithia-cyclopenta[a]indene-2-carboxylic acid methyl ester (30 mg, 0.07 mmol) in THF/H2O (1.5 mL/0.5 mL) was added 2.0M LiOH (0.15 mL, 0.35 mmol). The reaction was allowed to stir at ambient temperature over a 16-hour period, after which it was judged complete by LCMS. The THF was removed in vacuo and the resultant aqueous solution was acidified to pH ˜1-2 using 10% HCl to precipitate the desired compound which was filtered, rinsed with water, and oven-dried (55° C.). No purification was necessary. (Yield=20 mg, 71%)
