Methyl[2-(pyridin-4-yl)ethyl]amine → 2-(N'-Pyrid-4-ylethyl-N'-methylureido)dibenzothiophene

Participants

Reaction Steps

2-(4-Nitrobenzoxycarbonylamino)dibenzothiophene (Example 1; 501 mg, 1.35 mmol) was suspended in EtOAc (10 ml) and 4-[2-(methylamino)ethyl]pyridine (408 mg, 3.0 mmol) added in one portion. The resulting mixture was stirred at ambient temperature for 16 hours then further EtOAc (50 ml) added. The solution was washed with 1 M sodium hydroxide (3×25 ml), water (2×25 ml) and brine (25 ml), dried and evaporated in vacuo. NMR 8.44 (m, 3H), 8.34 (d, 1H), 8.13 (m, 1H), 7.96 (m, 1H), 7.82 (d, 1H), 7.55 (dd, 1H), 7.47 (m, 2H), 7.28 (d, 2H), 3.61 (t, 2H), 2.96 (s, 3H), 2.86 (t, 2H); m/z 362.
