Procedure

A solution of tert-butyl 4-[N-((6RS)-2-(2,2-dimethylpropionyloxymethyl)-4-oxo-3,4,7,8-tetrahydro-6H-cyclopenta[g]quinazolin-6-yl)-N-(prop-2-ynyl)amino]-benzoate (80 mg, 0.15 mmol) in trifluoroacetic acid (5 ml) was stirred at room temperature with protection from the light for 1.5 h. The solvent was removed in vacuo and the residue triturated with 1:1 diethyl ether and hexane to yield the desired product as a white solid (81 mg, TFA salt); m.p. 133° C.; 1H-NMR (DMSO-d6) δ 1.23 (s, 9H, CO2CMe3), 2.22 (m, 1H, 7-H), 2.50 (m, 1H, 7-H), 3.03 (m, 2H, 8-H), 3.14 (s, 1H, propargyl CH), 3.97 (AB system, J=18.8 Hz, 2H, propargyl CH2), 4.95 (s, 2H, 2-CH2), 5.79 (t, J=8.6 Hz, 1H, 6-H), 7.03 (d, J=9.0 Hz, 2H, 3′-H, 5′-H), 7.51 (s, 1H, 9-H), 7.81 (d, J=6.6 Hz, 2H, 2′-H, 6′-H), 7.83 (s, 1H, 5-H).
