Procedure
To a solution of 1.55 g of 4-(aminomethyl) -1-[[2-(diethylamino)ethyl]amino]-7-methoxythioxanthen-9-one in 40 mL of chloroform containing 2 mL of triethylamine chilled to 0° C. was added 0.45 mL of methyl chloroformate and the mixture was stirred at room temperature for several hours. The solvent was removed in vacuo, the residue was purified by flash chromatography (silica gel; eluting with chloroform, then 1% triethylamine in chloroform/hexane (1:1)) affording 1.2 g of methyl N-[[1-[[2-(diethylamino) ethyl]amino]-7-methoxy-9-oxothioxanthen-4-yl]methyl]carbamate which was recrystallized from ethyl acetate to yield 0.79 g of a bright yellow solid, m.p. 131°-132° C.
