1.725 g (3.358 mmol) of the compound from example 41 were dissolved in 7 ml of diiodomethane and admixed with 7.19 ml (53.732 mmol) of isopentyl nitrite. The reaction mixture was heated to 85° C. for 16 h and, after cooling, concentrated on a rotary evaporator. The residue was by means of preparative HPLC (eluent: water/acetonitrile/water with 1% trifluoroacetic acid, gradient 55:40:5→0:95:5). 64 mg of the title compound were obtained (4% of theory).
