A suspension of adamantan-1-ylcyanamide (151 mg, 0.857 mmol) and o-toluidine hydrochloride (186 mg, 0.857 mmol) in dry chlorobenzene was heated between 100°-130° C. for 4.5 hrs. The chlorobenzene was evaporated in vacuo with heating and the residue (285 mg) taken up in 18 ml of water. A gummy, insoluble material was discarded. On adjusting the aqueous extract to pH 9-9.5, a precipitate formed (194 mg, 71%). Two recrystallizations from EtOH/H2O gave the analytical sample; mp 160°-161°, 1H (CD3OD) 1.742 (s, 6 H), 2.050 (d, 6H, J=2.4 Hz), 2.029 (s, 3 H), 6.956 (j, 1 H, J=8.1 Hz), 7.056 (t, 1H, J=8.1 Hz), 7.168 (t, 1H, J=7.5 Hz), 7.213 (d, 1H, J=7.5 Hz). Anal. Calcd for C18H25N3 : C, 76.28; H, 8.89; N, 14.83. Found: C, 76.25; H, 8.86; N, 14.60.
