Example 26Synthesis of 2-(3-((7-methoxy-3-(2-(methylamino)pyrimidin-4-yl)naphthalen-1-yl)amino)propyl)isoindoline-1,3-dione (181) To a slurry of 4-(4-amino-6-methoxynaphthalen-2-yl)-N-methylpyrimidin-2-amine (150 mg, 0.42 mmol) in 1,2-dichloromethane (10 ml) was added N,N-diisopropylethylamine (250 mul) followed by acetic acid (0.5 ml), 3-(1,3-dioxoisoindolin-2-yl)propanal (140 mg) and sodium triacetoxyborohydride (200 mg). The mixture was stirred at room temperature for 24 hours before being poured into ethyl acetate (100 ml) washed with water (250 ml) and dried over anhydrous magnesium sulfate. Evaporation to dryness gave a yellow oil which was purified by silica gel chromatography eluting with 40-60% ethyl acetate in hexanes to yield 2-(3-((7-methoxy-3-(2-(methylamino)pyrimidin-4-yl)naphthalen-1-yl)amino)propyl)isoindoline-1,3-dione 181 as a yellow foam (95 mg). 1H NMR (CDCl3) 400 MHz delta 8.34 (d, J=5.2 Hz, 1H), 7.87 (s, 1H), 7.86-7.83 (m, 3H), 7.8 (d, J=8.8 Hz, 1H), 7.75-7.71 (m, 2H), 7.34 (s, 1H), 7.31 (d, J=2.4 Hz, 1H), 7.18 (dd, J=2.4 and 8.8 Hz, 1H), 7.08 (d, J=4.8 Hz, 1H), 5.24 (m, 1H), 4.9 (m, 1H), 4.04 (s, 3H), 3.9 (t, J=6.0 Hz 2H), 3.5 (t, J=6.0 Hz, 2H), 3.11 (d, J=5.2 Hz, 3H), 2.24 (m, 2H), 2.2-2.14 (m, 2H), LCMS m/e 468 (M+H)
The chemical industry reduces the impact on the environment during synthesis 3-(1,3-Dioxoisoindolin-2-yl)propanal. I believe this compound will play a more active role in future production and life.
