実験手順
To a stirred solution of N2-[4-(aminomethyl)phenyl]-9-fluoro-5,6-dihydro-4H-benzo-[6,7]cyclohepta[d][1,3]thiazol-2-amine-tert-butyl N-(4-aminobenzyl)carbamate (6.00 g, 27.0 mmol) in anhydrous THF (50 ml) was added benzoylisothiocyanate (4.43 g, 27.0 mmol). The solution was stirred for 2 hours and the solvent removed in vacuo to yield 100% (10.4 g) of the protected thiourea as a yellow solid: m.p. 161-163° C. 1H-NMR (CDCl3) δ 1.45 (9H, s), 4.33 (2H, d), 4.85 (1H, broad), 7.34 (2H, d), 7.60 (5H, m), 7.90 (2H, d), 9.13 (1H, s), 12.58 (1H, s); 386 (ESMS, MH+).
