実験手順

Adamantan-1-ylcyanamide (299 mg, 1.70 mmol) and o-iodoaniline hydrochloride (433 mg 1.70 mmol) were finely ground together and heated at 200° for 10 min. The resultant black glassy solid was pulverized, and recrystallized 5 times from EtOH/Et2O. The resultant faintly blue needles (80 mg) were dissolved in 4 ml EtOH, and passed through a short (< 1 cm) column packed from bottom to top with Celite, charcoal, activated alumina, and sand. The colorless eluate was then diluted with 5ml Et2O, and allowed to stand in an Et2O diffusion chamber overnight. The white needles were collected by suction filtration, 40 mg, mp 274°-275° C. Addition of another 5 ml Et2O yielded a second crop (31 mg) of identical material. Combined yield: 21%. 1H (CD3OD) 1.779 (s, 6H), 2.090 (s, 6H), 2.164 (s, 3 H), 7.168 (t, 1H, J=8.1 Hz), 7.388 (d, 1 H, J=9.1 Hz), 7.503 (t, 1 H, J=7.8 Hz), 8.004 (d, 1 H, J=7.8 Hz).
