Yield: 28%

Reaction Conditions:

with hydrogenchloride in ethyl acetate at 25; for 16 h;

Steps:

4 Step 4: l-methyl-4,5,6,7-tetrahydro-lH-pyrazolo[3,4-c]pyridine
To a stirred mixture of tert-butyl l-methyl-4,5-dihydro-lH-pyrazolo[3,4- c]pyridine-6(7H)-carboxylate (744 mg, 3.14 mmol) in EA (2 mL) was added HC1/EA(3 N, 4 mL). The mixture was stirred at 25°C for 16 hours. The reaction mixture was then concentrated and the residue purified by Prep-HPLC and SFC to afford the target compound as colorless oil which was used without further purification in the next step. (120 mg; yield 28%). LCMS (m/z): 138.10 (M+l).
