Participants

Reaction Steps

A solution of tert-butyl(1-(4-(3-(methoxymethyl)-2-oxo-7-phenyl-2,3-dihydro-1H-pyrido[2,3-b][1,4]oxazin-6-yl)phenyl)cyclobutyl)carbamate (60 mg, 0.116 mmol) in DMF (2 ml) was added potassium carbonate (48 mg) and 2-bromoacetonitrile (41.9 mg, 0.349 mmol). The reaction mixture was stirred at room temperature for 16 h then was diluted with ethyl acetate (20 ml). Washed with water, brine, and dried with Na2SO4, filtered and concentrated to give crude product which was purified by column (biotage, 25 g) eluted with ethyl acetate and cyclohexane to afford product (35 mg). 1H NMR (500 MHz, CDCl3): 7.20-7.33 (m, 10H), 5.10 (t, 1H), 4.97 (s, 1H), 4.82 (dd, 2H), 4.03 (dd, 2H), 3.36 (s, 3H), 2.44-2.50 (m, 4H), 2.06 (m, 1H), 1.80 (m, 1H), 1.24-1.36 (br, 9H).
