Reaction Steps
The Boc-protected intermediate 11a (0.87 g, 3.07 mmol) was stirred in dichloromethane (10 mL) and treated with 10 mL of a 2.53 M solution of HCl in EtOH. After warming to 35° C. for 2 hours, the mixture was concentrated under vacuum. The product was precipitated from IPA:MTBE (1:10). The product was recrystallized from IPA:MTBE three times to afford a high purity sample (42 mg) of white solid. MS (ESI) m/z 184 [M+1]+. NMR (CDCl3) δ 1.68-1.91 (m, 3H), 2.13-2.20 (d, 1H), 2.58 (s, 3H), 2.87-2.95 (dt, 1H), 3.14 (t, 1H), 3.25-3.28 (d, 1H), 3.54-3.59 (d, 1H), 3.65-3.73 (m, 1H), 9.10 (s, 2H).
