Ep the aqueous phase basic. The combined extracts had been washed with sat. brine, dried, and concentrated to a viscous oil that was pumped in vacuo 2 h to leave 700 mg (91 ) of 6a as a pale orange viscous oil, shown by HPLC to be 94 pure. Processing a modest level of product by re-dissolving it in 2N aq. HCl followed by further remedy as above offered 6a that was 96 pure by HPLC.

The mixture was stirred for 10 min and then filtered by means of a cotton plug to take away a few insolubles. The filtrate was concentrated to a residue that was redissolved in dichloromethane/hexane and after that concentrated to a yellow strong that was triturated in hexane.NH125 Epigenetics The solids had been collected and dried to leave 100 mg (97 ) of 6a dihydrochloride. 1H NMR (400 MHz, DMSO-d6): 10.02 (s, 2H), 7.37 (d, J = 8.2 Hz, 2H), 7.30.19 (m, 5H), 7.08 (d, J = 8.3 Hz, 2H), six.90 (d, J = 8.four Hz, 2H), 6.84 (d, J = eight.four Hz, 2H), 4.39 (t, J = five.eight Hz, 2H), 4.8-Hydroxyguanosine Cancer 28 (t, J = five.PMID:23439434 2 Hz, 2H), three.51 (t, J = 6.7 Hz, 2H), three.43 (t, J = six.two Hz, 2H), 3.25.08 (m, 8H), 1.25.17 (m, 12H). MS TOFES+: m/z 512.4 (M+H)+. 6.11 three,3-Bis(4-(2-morpholinoethoxy)phenyl)-2-phenylacrylonitrile, dihydrochloride (6b) The anion of phenylacetonitrile (36.2 mmol) was generated in THF (45mL) as described under for the synthesis of 6c. The ketone 5b (800 mg, 1.eight mmol) in THF (15 mL) was added more than a period of 5 min, the solution allowed to progressively warm to area temperature over 2 h and maintained there for 18 h. The mixture was poured into one hundred mL of ice-cold 3N aq. HCl, stirred for 30 min, and washed with ether (2x). The aqueous phase was produced strongly fundamental with 15 aq. NaOH, and extracted with ethyl acetate (3x). The combined extracts had been washed with water and then sat. brine, dried, and concentrated to leave a clear amber syrup (960 mg, 98 ), which crystallized upon standing at room temperature over many days. The solids were triturated in ethanol with sonication, collected, washed with ethanol, and dried to leave 6b (0.54g, 55 ) as a pale yellow powder, mp 13031 .

The dihydrochloride salt was prepared as follows: A answer of 6b (100 mg, 0.19 mmol) in dichloromethane at room temperature was treated dropwise with anhydrous HCl (0.39 mL, 1M in ether) plus the resulting gummy suspension was concentrated. The residue was triturated in ether to provide a glassy solid that.
