A solution of 2-(2-(tert-butyldiphenylsilyloxy)ethyl)-5,6,7,8-tetrahydroquinazolin-5-amine (570 mg, 1.32 mmol) in 10 mL of THF at 0° C. was treated with a 1M TBAF solution in THF (1.56 mL, 1.56 mmol). After stirring at room temperature overnight, the reaction mixture was directly submitted to flash chomatograph (SiO2, EtOAc to EtOAc/MeOH=100:15 to EtOAc/2M NH3 in MeOH=1:1) to give crude product as a white solid.
