Procedure

The mixture of Example 122 (38 mg, 0.061 mmol) and formaldehyde (0.046 ml, 37% solution, 10 eq, 0.612 mmol) was heated for 15 h in EtOH (1 mL) at 80° C. The reaction mixture was concentrated to dryness and the residue was purified by Combi-Flash Companion™ (Isco Inc.) column chromatography (SiO2; gradient elution, DCM/[DCM/MeOH 9: 1] 1:0→0:1) yielding the title compound as a colorless solid (31 mg, 0.048 mmol, 79%). HPLC: FtRet=1.236; LC-MS: m/z 646.4 [M+H]+.
