With hydrogenchloride In 1,4-dioxane at 20℃; for 12h;
1.3 Step 3 : 3-(aminomethyl)-1-benzylpyridin-2( 111)-one
Step 3 : 3-(aminomethyl)-1-benzylpyridin-2( 111)-one Tert-butyl ((1 -benzyl-2-oxo- 1 ,2-dihydropyridin-3-yl)methyl)carhamate (2.6 g. 0.00828 mol,Preparation 1,step-2) was dissolved in 4N 1,4-dioxane/HC1 (20 mL) and stirred at RT for about12 h. Excess solvent was removed in vaccuo and the crude material was triturated with ether (2 x100 inL) to afford 3-(aminornethyl)-1-benzylpyridiri-2(1H)-one 2.0 g (90 %) as off white solid.‘H NMR (400 MHz, DMSO-d6) : 8.187 (hs,IH), 7.937-7.915 (dd, J=21-{z,1H), 7.648-7.628 (dd, J=2Hz,1H), 7.350-7.289 (m,5H), 6.382-6.348 (t, J6.8Hz, IH), 5.171 (s,21-1). 3.858-3.8 15 (m2H), MS m/z : 428.3(M+F1)4,
