Procedure

The compound produced in Example 2 [photosensitive material C] (2 g) was added to a mixture of water (40 g) and phosphoric acid (0.5 g), and the resultant mixture was stirred at 20° C. for 5 hours, to thereby remove the acetal protective group. Thereafter, the temperature of the deprotected mixture was adjusted to 10° C. and neutralized with 1 weight % aqueous sodium hydroxide to a pH of 8. The precipitates formed through neutralization were immediately separated through filtration and dried, to thereby yield 1 g of photosensitive material F as a target compound.
