89% | Stage #1: With sodium hydroxide In methanol; water at 20℃; for 12 h; Stage #2: With hydrogenchloride In water |
Dissolve preparation 26 (983mg, 4.4mmol) in methanol (10ml) and add to this 1N NaOH (10ml). Stir at room temperature for 12 hrs. Then, evaporate the solvent, dissolve the residue in 1N HC1 (20 ml), and extract with ethyl acetate. Combine the organics, dry over MgSO4, and evaporate. Use this crude product (767. 5mg, 89percent) without further purification. MS = 195 (M-H-); 214 (M+NH4+). |
