Reaction Conditions

Reaction Steps

To a solution of 2,6-diisopropyl-4-morpholin-4-yl-phenylamine (279 mg) and pyridine (245 μL) in tetrahydrofuran (2 mL) was added cyclopentylacetyl chloride (210 mL) and the mixture was stirred for 1 hour at 25° C. The reaction mixture was diluted with ethyl acetate (20 mL) and washed with 10% aqueous sodium bicarbonate (20 mL) and brine (20 mL). The organic phase was dried over sodium sulfate, concentrated in vacuo and purified by flash chromatography. Recrystallisation of the crude brown material from hot ethyl acetate/heptane furnished 122 mg (33%) of the title compound as a white solid. LC-MS (m/z) 373 (MH+); tR=2.58, (UV, ELSD) 98%, 99%. 1H NMR (500 MHz, CDCl3): 1.19 (d, 12H), 1.27 (m, 2H), 1.60 (m, 2H), 1.68 (m, 2H), 1.93 (m, 2H), 2.40 (m, 1H), 2.41 (m, 2H), 3.05 (m, 2H), 3.17 (m, 4H), 3.87 (m, 4H), 6.49 (s, 1H), 6.70 (s, 2H).
