Procedure
Potassium fluoride (0.38 mmol) was added to a stirred solution of the product of stage f) (0.19 mmol) in aqueous N,N-dimethylformamide (2 ml N,N-dimethylformamide/0.2 ml water) at 0° C. After 10 min the reaction was allowed to warm to room temperature and stirred for 2 h. The reaction mixture was diluted with ethyl acetate and washed with water, 1 N hydrochloric acid (3 times) and brine. The organic layer was dried (MgSO4) and concentrated to give the title compound as a solid; 1H NMR (400MHz, CDCl3): δ=1.05 (t, 3H), 1.30 (t, 3H), 1.43 (s, 9H), 1.88-2.00 (m, 2H), 2H), 3.19 (s, 1H), 4.35 (app t, 2H), 4.52 (app t, 2H), 4.60-4.80 (br s, 2H), 5.22 (t, 1H), 8.39 (s, 1H), 8.80 (s, 1H), 10.75 (br s, 1H); LRMS (TSP—positive ion) 496 (MNH4+).
