Versuchsvorschrift

To an opaque brown solution of Intermediate A (371 mg, 2.28 mmol) in dry DMF (5 mL) under N2 was added sodium hydride (60% dispersion in mineral oil, 273 mg, 6.83 mmol) and the resulting mixture stirred at RT for 30 min. (CARE: gas evolution) A solution of Intermediate 148c (448 mg, 1.82 mmol) in dry DMF (5 mL) was added and the resulting dark brown solution stirred at 60° C. for 1 h. The solution was cooled to RT, then water (0.2 mL) added (CARE: gas evolution) and the mixture concentrated in vacuo. The residue was redissolved in MeOH (10 mL), applied to an SCX-2 cartridge (25 g) and washed with MeOH (100 mL). The product was eluted with 2M NH3 in MeOH (75 mL); concentration in vacuo left a dark brown gum. Flash chromatography (silica 40 g, 4-7% [2M NH3 in MeOH] in DCM) gave the title compound as a pale brown foam (446 mg, 63%). LCMS (Method 3): Rt 2.31 min, m/z 390 [MH+].
