Reaction Steps

Ethyl 5-chloro-6-(1-pyrrolidinyl)-3-pyridinecarboxylate (D14) (1.06 g, 4.16 mmol) in ethanol (20 mL) and aqueous sodium hydroxide (2M, 2.08 mL, 4.16 mmol) was heated at 40° C. for 18 h. The reaction mixture was allowed to cool and was neutralised with 2M HCl (aq.). The title compound formed as a white solid and was filtered off and washed with methanol to give the title compound (243 mg, 1.08 mmol) SJ108923-113A3. The filtrate was trapped on an SCX column, eluting with 2M ammonia in methanol to give further title compound as an orange solid (467 mg, 2.07 mmol). δH (methanol-d4, 400 MHz): 8.55 (1H, d), 8.03 (1H, d), 3.76-3.70 (4H, m), 1.96-1.90 (4H, m). MS (ES): C10H11ClN2O2 requires 226, 228; found 227, 229 (MH+).
