Reaction Steps

A solution of crude N-butyl-7-(trans-4-((tert-butyldimethylsilyl)oxy)cyclohexyl)-5-(4-fluorophenyl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine in MeOH (2.0 mL) was added a concentrated HCl solution (3 drops, 37% in water). The resulting solution was stirred at room temperature overnight, then concentrated. The residue was purified by pre-HPLC to provide the desired product (UNC1671A) (0.025 g, 36% over 3 steps). 1H NMR (400 MHz, CD3OD) δ 8.73 (s, 1H), 7.80 (s, 1H), 7.69-7.62 (m, 2H), 7.24-7.16 (m, 2H), 4.64-4.52 (m, 1H), 3.79-3.67 (m, 1H), 3.55 (t, J=7.1 Hz, 2H), 2.18-2.11 (m, 2H), 2.11-2.01 (m, 4H), 1.77-1.66 (m, 2H), 1.59-1.44 (m, 4H), 1.03 (t, J=7.4 Hz, 3H); MS m/z 383.2 [M+H]+.
