実験手順

42ELH89 (0.25 g, 0.67 mmol, 1.0 eq) was transferred to a 4 ml vial and dissolved in acetonitrile (2 ml). Isopropyl bromide (0.25 g, 3.0 eq.) was added along with Hünigs base (0.87 g, 10.0 eq.). The vial was sealed and shaken for 4 days at 60° C. The reaction mixture was transferred to a separatory funnel with distilled water and CH2Cl2. The aqueous phase was made basic with sodium hydrogen carbonate and extracted with dichloromethane (3 times). The organic layers were collected and dried with sodium sulfate and concentrated, this resulted in a yellow oil. The product was purified by flash chromatography (3% MeOH in CH2Cl2). The resulting product was dissolved in dichloromethane (1 ml) and HCl (1 eq. 2 M HCl in ether) was added under stirring. The salt precipitated by addition of the dichloromethane solution into heptane. Concentration on the rotary evaporator returned the product as white crystals. Yield 101.2 mg (63%), UV/MS 94/96 (M+ 415), Rf 0.25 (3% MeOH/CH2Cl2).
