Adamantan-1-ylcyanamide (514 mg, 2.92 mmol), and cyclohexylamine hydrochloride (398 mg, 2.93 mmol) were finely ground together, and heated at 200° C. for 10 min. The resultant glassy solid was pulverized, and extracted twice with 50 ml boiling 5% HCl. The insoluble material was filtered, and dried. 346 mg, mp 264°-270° (p.h.b. 240° C.). On cooling the combined aqueous extracts to 25°, a white ppt. formed, and was filtered off, 56 mg. Combined crude yield: 44%. Crystallization of a 50 mg sample of the crude product from EtOH/Et2O afforded white needles (25 mg, mp 269°-271° C. (p.h.b. 240°), lit. 268°-269° C.). 1H (CD3OD) 1.208-1.474 (m, 5H), 1.744 (s, 9H), 1.967 (s, 8H), 2.119 (5, 3H), 3.434 (m, 1H), 13C (CD3OD) (broad band decoupled) 25.55, 26.26, 30.96, 33.74, 36.74, 42.73.
