Reaction Steps

To crude azaindole 66 (76 mg, 0.19 mmol) in EtOH (6 mL) was added 10% NaOH (1 mL) and the mixture was stirred in an oil bath (90° C.) for 2 h. The mixture was then cooled to r.t., diluted with AcOEt and saturated brine and partitioned. The aqueous layer was extracted with AcOEt (3×). The combined organic solutions were dried (MgSO4), filtered and concentrated. The residual yellow oil was purified by means of PTLC employing AcOEt as eluent to afford the azaindole 67 (16 mg, 31%); 1H NMR (400 MHz; CDCl3) δ 1.61-1.80 (m, 8H), 2.77 (t, J=7.6 Hz, 2H), 3.67 (t, J=6.6 Hz, 2H), 3.97 (s, 3H), 7.34 (d, J=1.9 Hz, 1H), 7.61 (s, 1H), 7.73 (d, J=0.6 Hz, 1H), 7.85 (d, J=1.8 Hz, 1H), 8.17 (d, J=1.8 Hz, 1H), 9.29 (br s, 1H).
