Procedure
A mixture of methyl 3-amino-4-chloro-2-[(3-hydroxypropyl)amino]benzoate (11.4 g, 44.2 mmol) and 5-isothiocyanato-2-methoxy-4,6-dimethylpyrimidine (17.3 g, 88.4 mmol) in tetrahydrofuran (170 mL) was stirred at 65° C. for 3 days. The mixture was concentrated in vacuo, and the residue was purified by flash column chromatography on silica gel eluting with a 50-100% ethyl acetate/n-hexane gradient mixture. The filtrate was concentrated in vacuo to give the title compound as a yellow amorphous (13.1 g, 28.9 mmol, 65%).
