Reaction Steps

Synthesis followed SP6 (iPrOH:DMSO 1:1, 1.2 eq. DIEA, 120° C., 48 h), using 200 μmol tert-butyldimethyl(4-(oxiran-2-ylmethoxy)phenoxy)silane and 1-(2-methylthieno[2,3-d]pyrimidin-4-yl)piperidin-4-amine HCl-salt to give O-silylated intermediate upon purification by prep. HPLC (reversed phase) and prep. TLC (1 mm silica gel, PE/CH2Cl2/MeOH 6:4:1) with 22% yield. Product was obtained by deprotection according to SP7 and purification by prep. HPLC (reversed phase) and prep. TLC (1 mm silica gel, PE/CH2Cl2/MeOH 3:7:1.5) with 25% yield.
