実験手順: 2-Chloro-4-morpholin-4-yl-thieno[2,3-d]pyrimidine-6-carbaldehyde was reacted with benzyl-methyl-piperidin-4-yl-amine (hydrochloride salt) using the general reductive amination procedure to yield benzyl-[1-(2-chloro-4-morpholin-4-yl-thieno[2,3-d]pyrimidin-6-ylmethyl)-piperidin-4-yl]-methyl-amine, which was reacted with 2-aminopyrimidine-5-boronic acid, pinacol ester in General Procedure A. Purification on silica yielded 396. NMR (CDCl3); 1.65-1.73 (2H, m), 1.79-1.83 (2H, m), 2.05-2.09 (2H, m), 2.20 (3H, s), 2.45-2.47 (1H, m); 3.02 (2H, d), 3.60 (2H, s), 3.78 (2H, s), 3.85-3.89 (4H, m), 3.92-3.96 (4H, m), 5.23 (2H, s, br.), 7.12 (1H, s), 7.23-7.24 (1H, m), 7.31-7.33 (4H, m), 9.30 (2H, s).

実験手順: 4-(Benzyl-methyl-amino)-piperidine-1-carboxylic acid tert-butyl ester was dissolved in DCM and methanol and 2.0M HCl in ether was added. After 3 hours the solvent was removed in vacuo and the residue was recrystallised from ethyl acetate/methanol to yield benzyl-methyl-piperidin-4-yl-amine (hydrochloride salt). After 3 hours the solvent was removed in vacuo the residue was recrystallised from ethyl acetate/methanol

実験手順: A solution of the product of Example 9 (155 mg), benzyl-methyl-piperidin-4-yl-amine (123 mg), and acetic acid (0.11 mL) in DCM (3 mL) was treated with sodium triacetoxyborohydride (190 mg). After 16 h, the resulting mixture was treated with 10% sodium hydroxide (5 mL) and extracted with DCM (3×10 mL). The combined organic phases were dried (sodium sulfate) and evaporated. Chromatography of the residue (1–5% 2 M methanolic ammonia/DCM) gave the title compound as a colorless oil (155 mg). 1H NMR (400 MHz, CDCl3): 7.31–7.28 (m, 4H), 7.24–7.18 (m, 3H), 6.84 (d, J=8.8 Hz, 2H), 3.99 (t, J=6.3 Hz, 2H), 3.56 (s, 2H), 3.42 (s, 2H), 2.94 (m, 2H), 2.47 (m, 2H), 2.40 (m, 4H), 2.19 (s, 3H), 2.01–1.88 (m, 4H), 1.77 (m, 2H), 1.67 (m, 2H), 1.59 (m, 4H), 1.44 (m, 2H). extracted with DCM (3×10 mL) The combined organic phases were dried (sodium sulfate) evaporated
