Versuchsvorschrift

According to the procedure described for the synthesis of 206e (Ackerley, N. et al. J. Med. Chem. 1995, 38, 1608-1628; Manley, P. W. et al. J. Med. Chem. 1987, 30, 1812-1818), 205c (500.0 g, 2.0 mol) was reacted with LiBH4 (65.0 g, 3.0 mol) and methanol (95.0 g, 3.0 mol) in CH2Cl2 (6.0 L) to afford 206c (417.0 g, 99%) as an oil. 1H NMR (CDCl3): δ 3.38 (t, 2H, J=7.4), 3.50-3.40 (br. s, 1H, OH), 3.22 (d, 2H, J=5.6), 1.85 (qv, 2H, J=7.4), 1.50-1.35 (m, 2H), 1.30-1.20 (m, 2H), 0.85 (s, 6H). 13C NMR (CDCl3) δ 71.4, 37.5, 34.9, 33.9, 33.4, 23.7, 22.4.
