Reaction Steps

To a stirred solution of 1-(5-benzoyl-pyrazin-2-yl)-3-(2-methoxy-5-methyl-phenyl)-urea (22 mg; 0.061 mmol) in methanol (1 mL) was added sodium borohydride (10 mg; 0.3 mmol). After stirring for 12 hours, the reaction diluted with 30 mL of ethyl acetate and washed with aqueous 10% sodium carbonate (1×30 mL), brine (30 mL), then dried (MgSO4), and filtered. The filtered material was concentrated under reduced pressure to yield a white solid (91% yield). 1H NMR (400 MHz, CDCl3) δ 8.48 (br s, 1H), 8.39 (s, 1H), 8.22 (s, 1H), 8.12 (s, 1H), 7.25-7.45 (n, 5H), 6.89 (d, 1H), 6.80 (d, 1H), 5.85 (d, 1H), 3.88 (s, 3H), 2.37 (s, 3H). LRMS (ESI, Positive) m/e 365.24 (M+1).
