Reaction Steps

To a solution of 2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidine (500 mg) in THF (20 mL) at −78° C. was added n-butyllithium (0.94 mL of a 2.5 M solution in hexanes) and the reaction stirred at −78° C. for 1 h. Then, acetaldehyde (0.33 mL) was added and the reaction allowed to warm to room temperature over 16 h. The reaction was quenched with water (20 mL) and extracted into dichloromethane (2×20 mL). The combined organics were dried (MgSO4) and reduced in vacuo to give 1-(2-chloro-4-morpholin-4-yl-thieno[3,2-d]pyrimidin-6-yl)-ethanol as a cream solid.
