Procedure
To rac-tert-Butyl 8-acetoxy-2,3-dip-tolyl-7,8-dihydropyrido[2,3-b]pyrazine-5(6H)-carboxylate (step 3)(110 mg, 0.232 mmol) in dichloromethane (5 ml) was added trifluoroacetic acid (0.089 ml, 1.161 mmol). The solution was stirred at room temperature for 4 hrs. To the reaction mixture was added a saturated aqueous sodium carbonate (2 ml) and the mixture was vigorously stirred for 10 minutes. The organic layer was separated and concentrated in vacuo to afford the title compound;
