実験手順

To a solution of 1-methyl-1-H-indol-7-ol (Chemstep, CAS: 47577-33-4, 0.98 g, 6.8 mmol) and 2-iodoethanol (Fluka, 1.60 g, 8.6 mmol)) in DMF abs. (10 mL) was added potassium carbonate (1.84 g, 13 mmol). The reaction mixture at rt for 20 h, then at 70° C. for 24 h, quenched with ice/water, extracted with ethyl acetate. The organics were washed, dried and concentrated, the residue chromatographed on silica gel using heptane/ethyl acetate as eluent to obtain the desired compound (0.82 g) as a creamy solid. MS (ISP): m/e 192.3 (M+H)+
