Reaction Steps

[3-(8-Isopropyl-5-methyl-6-oxo-5,6,7,8-tetrahydro-pteridin-2-ylamino)-5-(methylsulfonyl)-phenyl]-thiocarbamic acid ethyl ester (150 mg; 0.313 mmol) was dissolved in 1 ml of dry DMF, tert-butyl-cis-4-aminocyclohexylcarbamate (201 mg; 0.940 mmol) was added. The reaction mixture was stirred at 70° C., overnight, then, it was diluted with water. The precipitated formed was filtered, washed with water and dried in vacuo. 196 mg (0.311 mmol; 99% yield) of the desired compound to were obtained.
