Procedure

To a solution of N-{3-chloro-4-[(3-fluorobenzyl)oxy]phenyl}-2-piperidin-4-yl-4,5-dihydro-2H-pyrimido[5′,4′:4,5]thieno[2,3-e]indazol-6-amine (40 mg, 0.07 mmol, 1 eq) in THF (1 mL) was added acetone (8 mg, 0.14 mmol, 2 eq), sodium triacetoxyborohydride (23 mg, 0.11 mmol, 1.5 eq) and trace amount of acetic acid. It was stirred at rt for 16 h. The mixture was purified by preparative HPLC to yield the desired product (15.4 mg, 36%). 1H-NMR (DMSO-d6) δ 8.41 (broad, 1H), 8.32 (d, 1H), 8.01 (d, 1H), 7.74 (d, 1H), 7.5 (dd, 1H), 7.44 (m, 1H), 7.29 (m, 2H), 7.20 (d, 1H), 7.15 (m, 1H), 5.24 (s, 2H), 4.04 (m, 1H), 3.36 (m, 4H), 2.92 (m, 3H), 2.74 (m, 1H), 2.25 (m, 1H), 2.02 (m, 2H), 1.89 (m, 2H), 0.99 (d, 6H). LCMS RT=2.87 min; [M+H]+=603.2.
