Reaction Steps

The mixture of Example 131 (80 mg, 0.121 mmol) and formaldehyde (0.090 mL, 37% solution, 10 eq., 1.208 mmol) was heated for 5 h in 2-propanol (4 mL) at 85° C. The mixture was concentrated to dryness and the residue was purified by reversed phase column chromatography. The fractions containing the product were pooled and worked up (addition of NaHCO3), yielding the title compound as an off-white solid (46 mg, 0.068 mmol, >98%). HPLC: HtRet=1.40 min; LC-MS: m/z 674.2 [M+H]+.
