Reaction Steps

N*4*-Allyl-6-chloro-pyrimidine-4,5-diamine (0.20 g, 0.0011 mol) was taken in NMP (3 ml). Thiophene-2-carbonyl chloride (0.14 ml, 0.0013 mol) was added slowly at 0° C. and stirred for 2 hrs at same temperature. The reaction mixture was diluted with water (10 ml) and extracted with DCM (3×5 ml). The organic layer was washed with saturated NaHCO3 solution (10 ml), followed by brine (10 ml) and dried over Na2SO4. The solvent was removed to get thiophene-2-carboxylic acid (4-allylamino-6-chloro-pyrimidin-5-yl)-amide (0.281 g, 88%) as a pale yellow solid.
