Reaction Steps
To a solution of 2,4-dichloropyrimidine (0.15 g, 1.0 mmol), benzylamine (0.109 ml, 1.0 mmol) in THF was added DIPEA (0.526 ml, 3.0 mmol) and the reaction was heated at reflux for 2 hours resulting in formation of a 4:1 mixture of regioisomers (desired versus undesired) by TLC (5% Methanol:methylene chloride). The reaction was stripped down in vacuo and purified by silica column (eluent: 2% methanol:methylene chloride) giving 0.12 g (0.548 mmol) of desired product 10 in 54% yield. LC/MS(M+1)=220
