Treatment of 3-aminobenzyl alcohol (I) with isopropyl isocyanate produced urea (II). Mesylation of alcohol (III), followed by reaction with LiBr gave benzyl bromide (III). Then, alkylation of 3-azidobenzazepine (IV) with (III) under phase-transfer conditions afforded (V). The azido group of (V) was reduced to amine (VI) by catalytic hydrogenation over Pd/C. Subsequent treatment of (VI) with carbonyl diimidazole produced isocyanate (VII). This was finally converted to the target compound by condensation with 6-aminobenzothiazole (VIII).
