Versuchsvorschrift

In a manner similar to the preparation of N4-(3,4-ethylenedioxy)-5-fluoro-N2-[2-(hydroxymethyl)benzofuran-5-yl]-2,4-pyrimidinediamine, 2-chloro-5-fluoro-N4-(1,2,3,4-tetrahydro-1-oxonaphthalen-7-yl)-4-pyrimidineamine was reduced with Dibal-H to yield 2-chloro-5-fluoro-N4-(1,2,3,4-tetrahydro-1-hydroxynaphthalen-7-yl)-4-pyrimidineamine. 1H NMR (CDCl3): δ 8.05 (d, 1H, J=3.0 Hz), 7.59 (d, 1H, J=2.4 Hz), 7.14 (d, 1H, J=8.1 Hz), 6.93 (bs, 1H), 4.82-4.78 (m, 1H), 2.82-2.71 (m, 2H), 2.08-1.74 (m, 5H); 19F NMR (282 MHz, CDCl3): −44661; LCMS: purity: 94%; MS (m/e): 294 (MH+).
