Yield	Reaction Conditions	Operation in experiment
	With N-ethyl-N,N-diisopropylamine; In 1-methyl-pyrrolidin-2-one; at 180℃; for 2h;microwave irradiation;	A mixture of 3,6-dichloropyridazine (500mg) and(4/?)-3,4-dihydro-2H-chromen-4-ylamine (500mg) in lambda/-methyl-2-pyrrolidone (2.5ml) and Hunig's base (1.5ml) was heated in the microwave at 18O0C for two hours. The reaction mixture was diluted with ethyl acetate (50ml) and washed with water (3 x 25ml) then evaporated.The residue was loaded onto a Biotage Si 25+M column and purified using the Biotage SP4 eluting with 0 to 5% methanol/dichloromethane over 10CV to afford the title compound (422mg) as a brown solid.MS (ES) Ci3H1235CIN3O requires 261 ; found 262 [M+H]+
