Participants

Reaction Steps

In a round bottom flask containing 6-[6-amino-5-(4-phenoxy-phenyl)-pyrimidin-4-ylamino]-2-aza-spiro[3.3]heptane-2-carboxylic acid tert-butyl ester (167.23 mg; 0.35 mmol; 1.00 eq.) in methanol (5.00 ml) was added hydrogen chloride (1.80 ml; 3.53 mmol; 10.00 eq.). The reaction was stirred for 16 h before it was concentrated and purified by HPLC. The fractions containing the desired product were lyophilized to afford the title compound as a white solid (50.3 mg, 34%). HPLC purity: 95%. MS: m/z=374[M+H]+. 1H NMR (CD3OD) δ 8.25 (s, 1H), 7.10-7.44 (m, 8H), 4.60 (m, 1H), 4.20 (s, 2H), 4.01 (s, 2H), 2.69 (m, 2H), 2.32 (m, 2H).
